// CLASS:    MDagModifier
//
// *****************************************************************************
//
// CLASS DESCRIPTION (MDagModifier)
//
// An MDagModifier is used to change the structure DAG.  This
// includes adding nodes, making new connections, and removing existing
// connections.  An MDagModifier keeps track of all operations that it is
// used for, so that they can be undone or redone.  Calling undo causes an
// MDagModifier to undo all of the dependency graph changes that it has
// done.
