// ****************************************************************************
// Class: avtPolyhedralSplit
//
// Purpose:
//   This class contains a list of polyhedral cells that were split into zoo
//   cells and their split count. The class also contains methods for expanding
//   data arrays to account for the cell splitting.
//
// Notes:
//
// Programmer: Brad Whitlock
// Creation:   Fri Mar 12 11:29:46 PST 2010
//
// Modifications:
//   Brad Whitlock, Tue Oct 26 16:23:45 PDT 2010
//   I turned polyhedralSplit into a vector so we could add polyhedral split
//   information as we discover it.
//
//   Cyrus Harrison, Tue Oct  9 14:12:12 PDT 2012
//   Moved here from the SimV2 reader, since other db readers need
//   to use this functionality.
