// CLASS:    MFnSubdData
//
// *****************************************************************************
//
// CLASS DESCRIPTION (MFnSubdData)
//
// MFnSubdData allows the creation and manipulation of subdivision surface
// data objects for use in the dependency graph.
// 
// If a user written dependency node either accepts or produces subdivision
// surfaces, then this class is used to extract or create the data that
// comes from or goes to other dependency graph nodes. The
// MDataHandle::type method will return kSubdSurface when data of this type
// is present.
//
// If a node is receiving a subdivision surface via an input attribute, the
// asSubdSurface method of MDataHandle can be used to access that input 
// Subdivision Surface.
//
// If a node is to create a Subdivision Surface and send it via an output
// attribute, a
// new MFnSubdData must be instantiated and then the create method
// called to build the actual data block as an MObject.  This MObject should
// be passed to the MFnSubd::create method as the parentOrOwner parameter
// so that the Subdivision Surface will be constructed inside the data
// block.  The MDataHandle::set routine is then used to pass the data block
// down the connection.
