// Class: avtBOVFileFormat
//
// Purpose:
// Reads "brick of float" files.
//
// Programmer: Hank Childs
// Creation: May 12, 2003
//
// Modifications:
//
// Hank Childs, Fri Mar 4 16:02:03 PST 2005
// Added support for deferring reading in all of the TOC.
//
// Brad Whitlock, Thu Mar 16 14:54:01 PST 2006
// Added byte offset so we can skip past a header. I also added a new
// flag for dividing a brick into bricklets.
//
// Brad Whitlock, Thu May 4 09:36:53 PDT 2006
// Added support for double and int.
//
// Hank Childs, Thu Apr 24 13:29:41 PDT 2008
// Change char *'s to strings and float *'s to vector<double>.
//
// Jeremy Meredith, Thu Jul 24 14:55:41 EDT 2008
// Convert most int's to long longs to support >4GB files.
//
// Brad Whitlock, Wed Apr 8 09:40:02 PDT 2009
// I added short int support.
