// CLASS:    MFnComponentListData
//
// *****************************************************************************
//
// CLASS DESCRIPTION (MFnComponentListData)
//
// MFnComponentListData allows the creation and manipulation of component list
// (represented as MObjects) data objects for use in the dependency graph.
// 
// If a user written dependency node either accepts or produces MObjects
// containing component lists, then this class is used to extract or
// create the data that comes from or goes to other dependency graph
// nodes.  To access it, the MDataHandle::data method is used to get an
// MObject for the data and this should then be used to initialize an
// instance of MFnComponentListData.
