//! \ingroup OpenMaya MFn
//! \brief Base class for component function sets.
/*!
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.
