// CLASS:    MFnComponent
//
//    This is the base class for all function sets which deal with
//    component objects.
//
//    Components are MObjects which hold index information for shapes.
//    The component object does not contain any information about the
//    shape, it just contains index values and type information.
//
//    Components can be marked as complete meaning that the component
//    represents a complete set of indices from 0 to numElements-1;
//
//    Components come is 3 varieties based upon the dimensions of the
//    index. The types are single, double, and triple indexed.
//    Examples of these types are mesh vertices (single indexed),
//    nurbs surface CVs (double indexed), and lattice points (triple indexed).
//
//    To create, edit, or query a specific type of component, use the
//    derived classes MFnSingleIndexedComponent, MFnDoubleIndexedComponent,
//    and MFnTripleIndexedComponent.
