	 * Usage:
	 *
	 * ClassController::includeClass('MyClass');
	 *
	 * 1. Create a class with name MyClassCore with filename MyClass.php
	 * -- This class should contain the core functionality.
	 * 
	 * 2. Create a class MyClass that extends MyClassCore in subfolder overrides with filename MyClass.php
	 * -- This will contain functionality that will to override the core functionality.
	 * 
	 * 3. MyClass constructor should call super on MyClassCore. e.g: parent::__construct();
	 *
	 * Useful if you use source control and want to extend functionality without changing the code base for
	 * individual projects.  Regardless if a overriding class exists, you call MyClass and not MyClassCore.
