MStatus pointOnSubd::initialize()
//
// Description:
// This method is called to create and initialize all of the attributes
// and attribute dependencies for this node type. This is only called
// once when the node type is registered with Maya.
//
// Return Values:
// MS::kSuccess
// MS::kFailure
//
