Declare a new Gaudi property.

Parameters

property	Object holding the property value.
doc	Documentation string for the property.

This is the generic version, for types that do not derive from SG::VarHandleKey. It just forwards to the base class version of declareProperty.

Declare a new Gaudi property.

Parameters
