// ****************************************************************************
// Class: avtNETCDFReaderBase
//
// Purpose:
// This class is a base class for "Reader" classes. which I mean to distinguish
// as the class that does the actual NETCDF reading. The various FileFormat
// classes call a reader to do their work. There are MTSD and STSD versions
// of the FileFormat which call the same reader class. This permits the plugin
// to serve up the best avtFileFormatInterface for the data with respect to
// whether it is "MT" or "ST". Thus, the FileFormat classes become a very
// thin veneer on top of the Reader class. We do this mostly to work around a
// file grouping issue in avtDatabase where it can't group MT files. The other
// reason is that we don't want to have an ST or MT file format because we
// don't know which it is until the file is opened.
//
// Notes:

// Creation: Tue Oct 27 14:39:32 PDT 2009

// Modifications:
// Eric Brugger, Mon Nov 16 07:59:52 PST 2009
// I added ReadTimeAttribute and ReadCycleAttribute.
