-# Contributing to ChaiScript
-
-Thank you for contributing!
-
-# Pull Requests
-
-Please follow the existing style in the code you are patching.
-
- - two space indent
- - no tabs EVER
- - match the existing indentation level
- 
-All ChaiScript commits are run through a large set of builds and analysis on all supported platforms. Those results are posted on the 
-[build dashboard](http://chaiscript.com/ChaiScript-BuildResults/index.html). No PR will be accepted until all tests pass.
-
-The build system has full integration with GitHub and you will be notified automatically if all tests have passed.
-
-# Issues
-
-Please do not post a "chaiscript is too slow", "chaiscript compiles too slowly", or "chaiscript needs more documentation" issue
-without first reading the following notes.
-
-## ChaiScript is Too Slow
-
-We are actively working on constently improving the runtime performance of ChaiScript. With the performance being
-[monitored with each commit](http://chaiscript.com/ChaiScript-BuildResults/performance.html).
-
-If you feel you *must* post an issue about performance, please post a complete example that illustrates the exact case you
-feel should be better optimized.
-
-Any issue request regarding performance without a complete example of the issue experienced will be closed.
-
-## ChaiScript Compiles Too Slowly
-
-This is also something we are actively working on. If you need highly optimized build times, please see [this discussion
-on the discourse site](http://discourse.chaiscript.com/t/slow-build-times/94).
-
-## ChaiScript Needs More Documentation
-
-If you have a question that is not addressed in the [cheatsheet](https://github.com/ChaiScript/ChaiScript/blob/develop/cheatsheet.md) 
-please open an issue so we can get the Cheatsheet updated.

-# Introduction
-
-This document outlines the principles that drive the development of ChaiScript. ChaiScript does not intent to be the perfect tool for *every* situation, but it does intend to be a good general purpose tool for *most* situations.
-
-# Goals
-
-1. Trivially easy to integrate with C++ projects
-2. 0 external depenencies
-3. "Perfect" integration with C++
-   * Direct mapping between ChaiScript objects and C++ objects
-   * Direct mapping between ChaiScript functions and C++ functions
-   * Direct mapping between ChaiScript exceptions and C++ exceptions
-3. Never surprise the C++ developer
-   * Object lifetimes managed by the stack
-   * Familiar syntax to C++ developers
-4. Perform "well enough" to not get in the way
-
-
-# Alternatives
-
-## Sol2
-
-If you are looking for the fastest performing scripting language and don't mind Lua, you might want to consider [sol2](https://github.com/ThePhD/sol2).
-
-## SWIG
-
-If you are looking for the most flexible solution to be able to support multiple target languages, consider [SWIG](http://swig.org)

-# ChaiScript Versioning
-
-ChaiScript tries to follow the [Semantic Versioning](http://semver.org/) scheme. This basically means:
-
-  * Major Version Number: API changes / breaking changes
-  * Minor Version Number: New Features
-  * Patch Version Number: Minor changes / enhancements
-
-
-
-# Initializing ChaiScript
-
-```
-chaiscript::ChaiScript chai; // initializes ChaiScript, adding the standard ChaiScript types (map, string, ...)
-```
-
-Note that ChaiScript cannot be used as a global / static object unless it is being compiled with `CHAISCRIPT_NO_THREADS`.
-
-# Adding Things To The Engine
-
-## Adding a Function / Method / Member
-
-### General
-
-```cpp
-chai.add(chaiscript::fun(&function_name), "function_name");
-chai.add(chaiscript::fun(&Class::method_name), "method_name");
-chai.add(chaiscript::fun(&Class::member_name), "member_name");
-```
-
-### Bound Member Functions
-
-```cpp
-chai.add(chaiscript::fun(&Class::method_name, Class_instance_ptr), "method_name");
-chai.add(chaiscript::fun(&Class::member_name, Class_instance_ptr), "member_name");
-```
-
-### With Overloads
-
-#### Preferred
-
-```cpp
-chai.add(chaiscript::fun<ReturnType (ParamType1, ParamType2)>(&function_with_overloads), "function_name");
-```
-
-#### Alternative
-
-```cpp
-chai.add(chaiscript::fun(static_cast<ReturnType (*)(ParamType1, ParamType2)>(&function_with_overloads)), "function_name");
-```
-This overload technique is also used when exposing base members using derived type
-
-```cpp
-struct Base
-{
-  int data;
-};
-
-struct Derived : public Base
-{};
-
-chai.add(chaiscript::fun(static_cast<int(Derived::*)>(&Derived::data)), "data");
-```
-
-### Lambda
-
-```cpp
-chai.add(
-  chaiscript::fun<std::function<std::string (bool)>>(
-    [](bool type) {
-      if (type) { return "x"; }
-      else { return "y"; }
-    }), "function_name");
-```
-
-### Constructors
-
-```cpp
-chai.add(chaiscript::constructor<MyType ()>(), "MyType");
-chai.add(chaiscript::constructor<MyType (const MyType &)>(), "MyType");
-```
-
-## Adding Types
-
-It's not strictly necessary to add types, but it helps with many things. Cloning, better errors, etc.
-
-```cpp
-chai.add(chaiscript::user_type<MyClass>(), "MyClass");
-```
-
-## Adding Type Conversions
-
-User-defined type conversions are possible, defined in either script or in C++.
-
-
-
-### ChaiScript Defined Conversions
-
-Function objects (including lambdas) can be used to add type conversions
-from inside of ChaiScript:
-
-```
-add_type_conversion(type("string"), type("Type_Info"), fun(s) { return type(s); });
-```
-
-### C++ Defined Conversions
-
-Invoking a C++ type conversion possible with `static_cast`
-
-```cpp
-chai.add(chaiscript::type_conversion<T, bool>());
-```
-
-Calling a user-defined type conversion that takes a lambda
-
-```cpp
-chai.add(chaiscript::type_conversion<TestBaseType, Type2>([](const TestBaseType &t_bt) { /* return converted thing */ }));
-```
-
-### Class Hierarchies
-
-If you want objects to be convertable between base and derived classes, you must tell ChaiScript about the relationship.
-
-```cpp
-chai.add(chaiscript::base_class<Base, Derived>());
-```
-
-If you have multiple classes in your inheritance graph, you will probably want to tell ChaiScript about all relationships.
-
-```cpp
-chai.add(chaiscript::base_class<Base, Derived>());
-chai.add(chaiscript::base_class<Derived, MoreDerived>());
-chai.add(chaiscript::base_class<Base, MoreDerived>());
-```
-
-### Helpers
-
-A helper function exists for strongly typed and ChaiScript `Vector` function conversion definition:
-
-```
-chai.add(chaiscript::vector_conversion<std::vector<int>>());
-```
-
-A helper function also exists for strongly typed and ChaiScript `Map` function conversion definition:
-
-```
-chai.add(chaiscript::map_conversion<std::map<std::string, int>>());
-```
-
-
-
-This allows you to pass a ChaiScript function to a function requiring `std::vector<int>`
-
-## Adding Objects
-
-```
-chai.add(chaiscript::var(somevar), "somevar"); // copied in
-chai.add(chaiscript::var(std::ref(somevar)), "somevar"); // by reference, shared between C++ and chai
-auto shareddouble = std::make_shared<double>(4.3);
-chai.add(chaiscript::var(shareddouble), "shareddouble"); // by shared_ptr, shared between c++ and chai
-chai.add(chaiscript::const_var(somevar), "somevar"); // copied in and made const
-chai.add_global_const(chaiscript::const_var(somevar), "somevar"); // global const. Throws if value is non-const, throws if object exists
-chai.add_global(chaiscript::var(somevar), "somevar"); // global non-const, throws if object exists
-chai.set_global(chaiscript::var(somevar), "somevar"); // global non-const, overwrites existing object
-```
-
-## Adding Namespaces
-
-Namespaces will not be populated until `import` is called.
-This saves memory and computing costs if a namespace is not imported into every ChaiScript instance.
-
-```cpp
-chai.register_namespace([](chaiscript::Namespace& math) {
-    math["pi"] = chaiscript::const_var(3.14159);
-    math["sin"] = chaiscript::var(chaiscript::fun([](const double x) { return sin(x); })); },
-    "math");
-```
-
-Import namespace in ChaiScript
-```
-import("math")
-print(math.pi) // prints 3.14159
-```
-
-# Using STL
-ChaiScript recognizes many types from STL, but you have to add specific instantiation yourself.
-
-```cpp
-typedef std::vector<std::pair<int, std::string>> data_list;
-data_list my_list{ make_pair(0, "Hello"), make_pair(1, "World") };
-chai.add(chaiscript::bootstrap::standard_library::vector_type<data_list>("DataList"));
-chai.add(chaiscript::bootstrap::standard_library::pair_type<data_list::value_type>("DataElement"));
-chai.add(chaiscript::var(&my_list), "data_list");
-chai.eval(R"_(
-    for(var i=0; i<data_list.size(); ++i)
-    {
-      print(to_string(data_list[i].first) + " " + data_list[i].second)
-    }
-  )_");
-```
-
-# Executing Script
-
-## General
-
-```cpp
-chai.eval("print(\"Hello World\")");
-chai.eval(R"(print("Hello World"))");
-```
-
-## Unboxing Return Values
-
-Returns values are of the type `Boxed_Value` which is meant to be opaque to the programmer. Use one of the unboxing methods to access the internal data.
-
-### Prefered
-
-```cpp
-chai.eval<double>("5.3 + 2.1"); // returns 7.4 as a C++ double
-```
-
-### Alternative
-
-```cpp
-auto v = chai.eval("5.3 + 2.1");
-chai.boxed_cast<double>(v); // extracts double value from boxed_value and applies known conversions
-chaiscript::boxed_cast<double>(v); // free function version, does not know about conversions
-```
-
-### Converting Between Algebraic Types
-
-```cpp
-chaiscript::Boxed_Number(chai.eval("5.3 + 2.1")).get_as<int>(); // works with any number type
-// which is equivalent to, but much more automatic than:
-static_cast<int>(chai.eval<double>("5.3+2.1")); // this version only works if we know that it's a double
-```
-
-### Conversion Caveats
-
-Conversion to `std::shared_ptr<T> &` is supported for function calls, but if you attempt to keep a reference to a `shared_ptr<>` you might invoke undefined behavior
-
-```cpp
-// ok this is supported, you can register it with chaiscript engine
-void nullify_shared_ptr(std::shared_ptr<int> &t) {
-  t = nullptr
-}
-```
-
-```cpp
-int main()
-{
-  // do some stuff and create a chaiscript instance
-  std::shared_ptr<int> &ptr = chai.eval<std::shared_ptr<int> &>(somevalue);
-  // DO NOT do this. Taking a non-const reference to a shared_ptr is not 
-  // supported and causes undefined behavior in the chaiscript engine
-}
-```
-
-
-## Sharing Values
-
-```cpp
-double &d = chai.eval("var i = 5.2; i"); // d is now a reference to i in the script
-std::shared_ptr<double> d = chai.eval("var i = 5.2; i"); // same result but reference counted
-
-d = 3;
-chai.eval("print(i)"); // prints 3
-```
-
-## Catching Eval Errors
-
-```cpp
-try {
-  chai.eval("2.3 + \"String\"");
-} catch (const chaiscript::exception::eval_error &e) {
-  std::cout << "Error\n" << e.pretty_print() << '\n';
-}
-```
-
-## Catching Errors Thrown From Script
-
-```cpp
-try {
-  chai.eval("throw(runtime_error(\"error\"))", chaiscript::exception_specification<int, double, float, const std::string &, const std::exception &>());
-} catch (const double e) {
-} catch (int) {
-} catch (float) {
-} catch (const std::string &) {
-} catch (const std::exception &e) {
-  // This is the one that will be called in the specific throw() above
-}
-```
-
-## Sharing Functions
-
-
-```cpp
-auto p = chai.eval<std::function<std::string (double)>>("to_string"); 
-p(5); // calls chaiscript's 'to_string' function, returning std::string("5")
-```
-
-Note: backtick treats operators as normal functions
-
-```cpp
-auto p = chai.eval<std::function<int (int, int)>>("`+`"); 
-p(5, 6); // calls chaiscript's '+' function, returning 11
-```
-
-```cpp
-auto p = chai.eval<std::function<std::string (int, double)>>("fun(x,y) { to_string(x) + to_string(y); }");
-p(3,4.2); // evaluates the lambda function, returning the string "34.2" to C++
-```
-
-# Language Reference
-
-## Variables
-
-```
-var i; // uninitialized variable, can take any value on first assignment;
-auto j; // equiv to var
-
-var k = 5; // initialized to 5 (integer)
-var l := k; // reference to k
-auto &m = k; // reference to k
-
-global g = 5; // creates a global variable. If global already exists, it is not re-added
-global g = 2; // global 'g' now equals 2
-
-global g2;
-if (g2.is_var_undef()) { g2 = 4; } // only initialize g2 once, if global decl hit more than once
-
-GLOBAL g3; // all upper case version also accepted
-```
-
-## Looping
-
-```
-// c-style for loops
-for (var i = 0; i < 100; ++i) { print(i); }
-```
-
-```
-// while
-while (some_condition()) { /* do something */ }
-```
-
-```
-// ranged for
-for (i : [1, 2, 3]) { print(i); }
-```
-
-Each of the loop styles can be broken using the `break` statement. For example:
-
-```
-while (some_condition()) {
-  /* do something */
-  if (another_condition()) { break; }
-}
-```
-
-## Conditionals
-
-```
-if (expression) { }
-```
-
-```
-// C++17-style init-if blocks
-// Value of 'statement' is scoped for entire `if` block
-if (statement; expression) { }
-```
-
-## Switch Statements
-
-``` chaiscript
-var myvalue = 2
-switch (myvalue) {
-    case (1) {
-        print("My Value is 1");
-        break;
-    }
-    case (2) {
-        print("My Value is 2");
-        break;
-    }
-    default {
-        print("My Value is something else.";
-    }
-}
-```
-
-## Built-in Types
-
-There are a number of built-in types that are part of ChaiScript.
-
-### Vectors and Maps
-
-```
-var v = [1,2,3u,4ll,"16", `+`]; // creates vector of heterogenous values
-var m = ["a":1, "b":2]; // map of string:value pairs
-
-// Add a value to the vector by value.
-v.push_back(123);
-
-// Add an object to the vector by reference.
-v.push_back_ref(m);
-```
-
-### Numbers
-
-Floating point values default to `double` type and integers default to `int` type. All C++ suffixes
-such as `f`, `ll`, `u` as well as scientific notation are supported
-
-```
-1.0 // double
-1.0f // float
-1.0l // long double
-1 // int
-1u // unsigned int
-1ul // unsigned long
-1ull // unsigned long long
-```
-
-Literals are automatically sized, just as in C++. For example: `10000000000` is > 32bits and the appropriate type is used to hold it
-on your platform.
-
-
-## Functions
-
-Note that any type of ChaiScript function can be passed freely to C++ and automatically
-converted into a `std::function` object.
-
-### General 
-
-```
-def myfun(x, y) { x + y; } // last statement in body is the return value
-def myfun(x, y) { return x + y; } // equiv 
-```
-
-### Optionally Typed
-
-```
-def myfun(x, int y) { x + y; } // requires y to be an int
-```
-
-### With Guards
-
-```
-def myfun(x, int y) : y > 5 { x - y; } // only called if y > 5
-```
-
-### Methods
-
-Methods and functions are mostly equivalent
-
-```
-def string::add(int y) { this + to_string(y); }
-def add(string s, int y) { s + to_string(y); } //equiv functionality
-
-// calling new function/method
-"a".add(1); // returns a1
-add("a", 1); // returns a1, either calling syntax works with either def above
-```
-
-### Lambdas
-
-```
-var l = fun(x) { x * 15; }
-l(2) // returns 30
-
-var a = 13
-var m = fun[a](x) { x * a; } 
-m(3); // a was captured (by reference), returns 39
-
-var n = bind(fun(x,y) { x * y; }, _, 10);
-n(2); // returns 20 
-```
-
-
-
-## ChaiScript Defined Types
-
-Define a type called "MyType" with one member value "a" and a getter
-
-### Preferred
-
-```
-class MyType {
-  var value;
-  def MyType() { this.value = "a"; }
-  def get_value() { "Value Is: " + this.value; }
-};
-```
-
-### Alternative 
-
-```
-attr MyType::value;
-def MyType::MyType() { this.value = "a"; }
-def MyType::get_value() { "Value Is: " + this.value; }
-```
-
-### Using
-
-```
-var m = MyType(); // calls constructor
-print(m.get_value()); // prints "Value Is: a"
-print(get_value(m)); // prints "Value Is: a"
-```
-
-## Dynamic Objects
-
-All ChaiScript defined types and generic Dynamic_Object support dynamic parameters
-
-```
-var o = Dynamic_Object();
-o.f = fun(x) { print(x); }
-o.f(3); // prints "3"
-```
-
-Implicit 'this' is allowed:
-
-```
-var o = Dynamic_Object();
-o.x = 3;
-o.f = fun(y) { print(this.x + y); }
-o.f(10); // prints 13
-```
-
-## Namespaces
-
-Namespaces in ChaiScript are Dynamic Objects with global scope
-
-```
-namespace("math") // create a new namespace
-
-math.square = fun(x) { x * x } // add a function to the "math" namespace
-math.sum_squares = fun(x, y) { math.square(x) + math.square(y) }
-
-print(math.square(4)) // prints 16
-print(math.sum_squares(2, 5)) // prints 29
-```
-
-### Option Explicit
-
-If you want to disable dynamic parameter definitions, you can `set_explicit`.
-
-```
-class My_Class {
-  def My_Class() {
-    this.set_explicit(true);
-    this.x = 2; // this would fail with explicit set to true
-  }
-};
-```
-
-## method_missing
-
-A function of the signature `method_missing(object, name, param1, param2, param3)` will be called if an appropriate
-method cannot be found
-
-```
-def method_missing(int i, string name, Vector v) {
-  print("method_missing(${i}, ${name}), ${v.size()} params");
-}
-
-5.bob(1,2,3); // prints "method_missing(5, bob, 3 params)"
-```
-
-`method_missing` signature can be either 2 parameters or 3 parameters. If the signature contains two parameters
-it is treated as a property. If the property contains a function then additional parameters are passed to
-the contained function.
-
-If both a 2 parameter and a 3 parameter signature match, the 3 parameter function always wins.
-
-## Context
-
- * `__LINE__` Current file line number
- * `__FILE__` Full path of current file
- * `__CLASS__` Name of current class
- * `__FUNC__` Name of current function
-
-
-# Built-in Functions
-
-## Evaluation
-
-```
-eval("4 + 5") // dynamically eval script string and returns value of last statement
-eval_file("filename") // evals file and returns value of last statement
-use("filename") // evals file exactly once and returns value of last statement
-                // if the file had already been 'used' nothing happens and undefined is returned
-```
-
-Both `use` and `eval_file` search the 'usepaths' passed to the ChaiScript constructor
-
-## JSON
-
- * `from_json` converts a JSON string into its strongly typed (map, vector, int, double, string) representations
- * `to_json` converts a ChaiScript object (either a `Object` or one of map, vector, int, double, string) tree into its JSON string representation
- 
-## Extras
-ChaiScript itself does not provide a link to the math functions defined in `<cmath>`. You can either add them yourself, or use the [ChaiScript_Extras](https://github.com/ChaiScript/ChaiScript_Extras) helper library. (Which also provides some additional string functions.)

-Catch
------
-
-This module defines a function to help use the Catch test framework.
-
-The :command:`catch_discover_tests` discovers tests by asking the compiled test
-executable to enumerate its tests.  This does not require CMake to be re-run
-when tests change.  However, it may not work in a cross-compiling environment,
-and setting test properties is less convenient.
-
-This command is intended to replace use of :command:`add_test` to register
-tests, and will create a separate CTest test for each Catch test case.  Note
-that this is in some cases less efficient, as common set-up and tear-down logic
-cannot be shared by multiple test cases executing in the same instance.
-However, it provides more fine-grained pass/fail information to CTest, which is
-usually considered as more beneficial.  By default, the CTest test name is the
-same as the Catch name; see also ``TEST_PREFIX`` and ``TEST_SUFFIX``.
-
-.. command:: catch_discover_tests
-
-  Automatically add tests with CTest by querying the compiled test executable
-  for available tests::
-
-    catch_discover_tests(target
-                         [TEST_SPEC arg1...]
-                         [EXTRA_ARGS arg1...]
-                         [WORKING_DIRECTORY dir]
-                         [TEST_PREFIX prefix]
-                         [TEST_SUFFIX suffix]
-                         [PROPERTIES name1 value1...]
-                         [TEST_LIST var]
-    )
-
-  ``catch_discover_tests`` sets up a post-build command on the test executable
-  that generates the list of tests by parsing the output from running the test
-  with the ``--list-test-names-only`` argument.  This ensures that the full
-  list of tests is obtained.  Since test discovery occurs at build time, it is
-  not necessary to re-run CMake when the list of tests changes.
-  However, it requires that :prop_tgt:`CROSSCOMPILING_EMULATOR` is properly set
-  in order to function in a cross-compiling environment.
-
-  Additionally, setting properties on tests is somewhat less convenient, since
-  the tests are not available at CMake time.  Additional test properties may be
-  assigned to the set of tests as a whole using the ``PROPERTIES`` option.  If
-  more fine-grained test control is needed, custom content may be provided
-  through an external CTest script using the :prop_dir:`TEST_INCLUDE_FILES`
-  directory property.  The set of discovered tests is made accessible to such a
-  script via the ``<target>_TESTS`` variable.
-
-  The options are:
-
-  ``target``
-    Specifies the Catch executable, which must be a known CMake executable
-    target.  CMake will substitute the location of the built executable when
-    running the test.
-
-  ``TEST_SPEC arg1...``
-    Specifies test cases, wildcarded test cases, tags and tag expressions to
-    pass to the Catch executable with the ``--list-test-names-only`` argument.
-
-  ``EXTRA_ARGS arg1...``
-    Any extra arguments to pass on the command line to each test case.
-
-  ``WORKING_DIRECTORY dir``
-    Specifies the directory in which to run the discovered test cases.  If this
-    option is not provided, the current binary directory is used.
-
-  ``TEST_PREFIX prefix``
-    Specifies a ``prefix`` to be prepended to the name of each discovered test
-    case.  This can be useful when the same test executable is being used in
-    multiple calls to ``catch_discover_tests()`` but with different
-    ``TEST_SPEC`` or ``EXTRA_ARGS``.
-
-  ``TEST_SUFFIX suffix``
-    Similar to ``TEST_PREFIX`` except the ``suffix`` is appended to the name of
-    every discovered test case.  Both ``TEST_PREFIX`` and ``TEST_SUFFIX`` may
-    be specified.
-
-  ``PROPERTIES name1 value1...``
-    Specifies additional properties to be set on all tests discovered by this
-    invocation of ``catch_discover_tests``.
-
-  ``TEST_LIST var``
-    Make the list of tests available in the variable ``var``, rather than the
-    default ``<target>_TESTS``.  This can be useful when the same test
-    executable is being used in multiple calls to ``catch_discover_tests()``.
-    Note that this variable is only available in CTest.

+  /// relationship in all modules that use the newly added type in a polymorphic way.

+  /// class Derived : public Base

+  ///
+  /// chaiscript::ChaiScript chai;
