Documents the two-enum configuration system: Options (engine-level:
load_module, use, eval_file) and Library_Options (stdlib-level:
No_Stdlib, No_IO, No_Prelude, No_JSON), with usage examples for
both ChaiScript and ChaiScript_Basic constructors.

Resolved conflict in unittests/compiled_tests.cpp where both branches
added tests at the end of file (issue #146 tests and issue #421 tests).

Separate system-level options (No_Load_Modules, Load_Modules, No_External_Scripts,
External_Scripts) from library-level options (No_Stdlib, No_IO, No_Prelude, No_JSON)
into two distinct enum types. Add Library_Options as a parameter to the ChaiScript
constructor. Update tests to demonstrate both ChaiScript_Basic (explicit Std_Lib::library
call) and ChaiScript (library options via constructor parameter) usage.

* Fix#201: Add class inheritance support with Derived : Base syntax
Classes can now inherit methods and attributes from a base class using
C++-style syntax: `class Derived : Base { ... }`. Base class methods and
attributes are automatically available on derived objects. Derived classes
can override base methods by defining a method with the same name.
Inheritance relationships are tracked to support proper type matching
in the dispatch system.

* Address review: use implicit derived-to-base matching instead of copying base class functions
Instead of copying all base class methods/attributes into derived classes,
make the type matching system recognize inheritance relationships. Base class
methods now naturally match derived objects through dynamic_object_typename_match,
and dispatch ordering ensures derived overrides are preferred over base methods.
This is simpler (net -25 lines) and avoids duplicating function registrations.

* Add tests for passing derived objects to functions expecting Base
Tests cover: free functions calling base methods on derived objects,
polymorphic dispatch through containers, base attribute access on
derived objects, and multi-level inheritance (GrandChild : Derived : Base).

* Add typed parameter tests for class inheritance
Use typed function signatures (e.g., `def call_do_something(Base obj)`)
instead of untyped parameters to test that derived objects are accepted
by functions expecting a base type, with correct polymorphic dispatch.

Add both a compiled C++ test (with registered type_conversion) and a
pure ChaiScript test (with dynamic objects and custom == operator) to
verify that switch case comparisons properly manage object lifetimes.

Add Function_Push_Pop to Switch_AST_Node case comparison to properly
manage the lifetime of temporaries created during type conversions.
Make Binary_Operator_AST_Node::do_oper static and public so it can be
reused by Switch_AST_Node for case equality checks, ensuring consistent
lifetime management across all operator invocations.

Add new Options enum values (No_Stdlib, No_IO, No_Prelude, No_JSON) that
allow users to control which parts of the standard library are registered.
Std_Lib::library() now accepts an options vector, and the ChaiScript
convenience class forwards its options to the library builder. This enables
use cases where only custom functions should be exposed to script users.

The cheatsheet's "ChaiScript Defined Types" section was minimal, showing only
a basic class with one attribute and a getter. Expanded it to document block
syntax, open syntax, attribute keywords (var/attr/auto), constructor and method
guards, operator overloading, cloning, and added a test exercising all examples.

Add comprehensive reflection documentation to cheatsheet.md covering type
inspection, object methods, Type_Info, function introspection, system
introspection, and Dynamic_Object reflection. Add missing global reflection
functions (type_name, is_type, function_exists, get_functions, get_objects,
type, dump_system, dump_object) and is_type_arithmetic to the Doxygen
prelude docs. Include a thorough test exercising all documented features.

Fix this by replacing the lambda with a simple ternary operator
expression.
ChaiScript inherits from ChaiScript_Basic, so this is good practice.
I also need to be able to inherit from ChaiScript and dynamic cast, which is impossible without this destructor.
