//! \brief Base Class for User-defined Dependency Graph Geometry Data Types. 
/*!

  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.

  MP`xGeometryData 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.
