// 
// Specialization of HDF5WriterBase to collect and save data from
// moose model. The data is appended to an existing dataset at each
// process step. An explicit writing is also allowed via the flush
// command.  As soon as the data from a table is written to file, the
// table is cleared.
// 

// Change log:
// 
// 2012-02-25 15:50:03 (+0530) Subha - started coding this class
//
// Thu Jul 31 16:56:47 IST 2014 Subha - updating to use new API on
// async13 branch.
