+// CLASS DESCRIPTION (MFnGeometryData)
+// 
+// This class is the function set for geometry data.
+//
+// Geometry data adds matrix and grouping (set) information to regular data
+// and is used to pass geometry types such as mesh, lattice, and NURBS shape
+// data through DG connections.
+//
+// User defined geometry data types (MPxGeometryData) are also supported 
+// by this class.
+//
+// The matrix within geometry data is the matrix used to convert the object
+// into local space.
