// Overview:
//
//		The meshOp factory implements the actual meshOperation operation. 
//		It takes in three parameters:
//
//			1) A polygonal mesh
//			2) An array of component IDs
//          3) A mesh operation identifier
//
// Please refer to MFnMeshOperations to get more information on the different 
// mesh operations.
