// CLASS:    MFnDependencyNode
//
// *****************************************************************************
//
// CLASS DESCRIPTION (MFnDependencyNode)
//
//  MFnDependencyNode allows the creation and manipulation of dependency
//  graph nodes.  Traversal of the dependency graph is possible using the
//  getConnections method.
//
//  This function set does not support creation or removal of connections.  
//  MDGModifier should be used for that purpose.
