// Description:
//
// This class is specific to the Master connection and is optimized
// for the writer sequence and batch processing chain.  For the Slave
// implementation look for the ossimImageMpiSWriterSequenceConnection.cc and .h
// files.  The Master connection is currently implemented to allways do
// a recieve and does no processing itself.  The slave connection does
// all the actual work and processing.
