Added logic for every GHOP specific model. Defined logic for every model defined for GHOP. These logics do nothing special now. They are just inherited from their parent classes. Necessary GHOP specific logic will be added later as necessary. Reviewed by: Lennard de Rijk

    This exception is raised when an invalid index is encountered, and has
    the 'silent_variable_feature' attribute set to true.  This ensures that
    django's templates proceed to use the next lookup type gracefully when
    an Exception is raised.  Fixes ticket #4740.
