Additional information needed when CreateMaterial is exercized

[michelpons]

Currently the log for ICapeThermoMaterial::CreateMaterial shows typically:
MaterialObject <STREAM01> : Call to CreateMaterial
MaterialObject <STREAM01> : Return from CreateMaterial - Succeeded

while there is an output argument to the method call which is of type CapeInterface so it could be worth to indicate what is the pointer for the interface to the new Material Object.
