//
// CLASS DESCRIPTION (MFnSet)
//
//  MFnSet is the function set that is used for manipulating sets of objects.
//  Sets in Maya are dependency nodes, so it is possible for one set to 
//  contain others.
//
//  A set is a list of dependency nodes and dag nodes.  Sets are useful for
//  keeping track of lists of objects for many purposes such as selection
//  or applying common rendering parameters.  Sets in Maya are also dependency 
//  nodes, so it is possible for one set to contain others..
