Log Message:
-----------
Readd removed code that extends functionality
  of RegisterType().

RegisterGeneratedTypesWithMapping()
  Registers python classes so they can be 
    serialized and parsed as "any".
  Uses _RegisterTypeWithSchemaAndClass() and  
    _DynamicImport() functions.

+    Register a type by providing its schema and class.  This allows
