/**\class MakeDataException MakeDataException.h FWCore/Framework/interface/MakeDataException.h

Description: An exception that is thrown whenever a Proxy had a problem with
its algorithm.

 Usage:
This exception will be thrown automatically if a a class that inherits from
DataProxyTemplate<> returns 0 from its make method.

If you wish to explain the reason for the error, you can throw a 
MakeDataException from within your Proxy
E.g.
\code
if(outOfBoundsValue) {
   throw MakeDataException(" value out of bounds",
                           MakeDataExceptionInfo<record_type, value_type>(iDataKey));
}
\endcode
