* 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.

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.
I initially tried to use the existing .clang-format file,
but it does not match the code style (at least with clang-format 11)
and the formatting is not consistent across files.
Therefore, I decided to rewrite the .clang-format with some personal
preferences.
Used command
find . -iname "*.hpp" -o -iname "*.cpp" | xargs clang-format -i -style=file
