// Class: avtDDCMDFileFormat
//
// Purpose:
// Reads in DDCMD files as a plugin to VisIt.
//
// Programmer: brugger -- generated by xml2avt
// Creation: Fri Aug 31 15:27:59 PST 2007
//
// Modifications:
// Eric Brugger, Thu Jan 3 11:07:49 PST 2008
// I changed the destructor so that it is defined in the ".C" file.
//
// Eric Brugger, Tue Jul 15 15:19:36 PDT 2008
// I added support for the 'b' field type. This involved adding the method
// bFieldConvert and the variables labelSize, iSpeciesSize, labelUnsigned
// and iSpeciesUnsigned.
//
// Eric Brugger, Thu Nov 20 10:44:45 PST 2008
// I added the ability to read atom files, which required being able to
// read multiple files to get all the data.
//
// Eric Brugger, Fri Dec 5 16:37:44 PST 2008
// I enhanced the reader to read ascii atom files.
