* This class is used to provide an intermediate superclass for modules and classes that include

* module methods to the actual superclass. Multiple of these intermediate superclasses can be

* added for multiple included modules.

* This allows the normal superclass-based searches (searchMethod, getConstant, etc) to traverse

* the superclass ancestors as normal while the included modules do not actually show up in

* direct inheritance traversal.
