//  Class: avtKullLiteFileFormat
//
//  Purpose:
//      Handles files of the pdb file format.
//
//  Programmer: Akira Haddox
//  Creation:   June 18, 2002
//
//  Modifications:
//
//    Akira Haddox, Tue May 20 08:49:59 PDT 2003
//    Added in for dealing with mixed materials, removed code
//    that tried to deal with data variables.
//    
//    Hank Childs, Fri Jul 23 09:42:09 PDT 2004
//    Extended format to support 2D meshes.
//
//    Hank Childs, Mon Jul 26 08:59:40 PDT 2004
//    Add support for mesh tags.
//
//    Hank Childs, Tue Jun 14 16:31:33 PDT 2005
//    Add support for IsRZ.
//
//    Hank Childs, Thu May 11 08:52:27 PDT 2006
//    Add support for reading densities.
//
//    Brad Whitlock, Mon Aug 28 14:25:08 PST 2006
//    Added m_names_per_domain so we can know the materials defined on
//    each domain. This helps read density from MD files.
