//  Method: avtQueryableSource
//
//  Purpose:
//      A queryable source is one that is queryable.  All terminating sources
//      are considered queryable, ensuring that every pipeline has a
//      queryable source.
//
//  Programmer: Hank Childs
//  Creation:   July 28, 2003
//
//  Modifications:
//    Kathleen Bonnell, Wed Nov 12 18:26:21 PST 2003
//    Add virtual method 'FindElementForPoint'.
//
//    Kathleen Bonnell, Mon Dec 22 14:48:57 PST 2003 
//    Add virtual method 'GetDomainName'.
//
//    Hank Childs, Thu Feb  5 17:11:06 PST 2004
//    Moved inlined constructor and destructor definitions to .C files
//    because certain compilers have problems with them.
//
//    Kathleen Bonnell, Tue May 25 16:16:25 PDT 2004 
//    Add virtual method 'QueryZoneCenter'.
//
//    Kathleen Bonnell, Thu Jun 10 18:31:22 PDT 2004 
//    Renamed QueryZoneCenter to QueryCoords, added bool arg.
//
//    Kathleen Bonnell, Thu Dec 16 17:16:33 PST 2004 
//    Added another bool arg to QueryCoords. 
//
//    Kathleen Bonnell, Tue Jan 25 07:59:28 PST 2005 
//    Added const char *arg to QueryCoords.
