//  Class:  avtUnstructuredPointBoundaries
//
//  Purpose:
//    A domain boundaries for unstructured datasets which constructs
//    the boundaries from the list of shared points. When using this
//    class, only SetSharedPoints needs to be called. It will provide
//    the needed information to SetGivenCellsAndPoints.
//
//  Notes:
//    This class is based on the assumption that ExchangeMesh or
//    ConfirmMesh will be called before any of the other Exchange
//    methods.

//  Programmer:  Akira Haddox
//  Creation:    August 11, 2003
