+//
+// CLASS DESCRIPTION (MPxGeometryData)
+//
+// This class is used to provide a wrapper or container for some arbitrary
+// geometry type that you have defined. This allows your data type to exist as
+// typed attributes on dependency nodes and to be passed through dependency
+// graph connections.
+// 
+// MPxGeometryData is similar to MPxData but includes methods to support sets
+// (also known as groups) and component iteration.
+// 
+// For user defined shapes (MPxSurfaceShape derived classes), in order to
+// support maya's deformers you must declare an MPxGeometryData class as well
+// as a geometry iterator (MPxGeometryIterator).
+// 
+// To register geometry data use MFnPlugin::registerData with the type argument
+// equal to MPxData::kGeometryData.
