 * Initialize FVM to time plot file writer.
 *
 * Options are:

 *   dat                 output dat (space-separated) files
 *   use_iteration       use time step id instead of time value for
 *                       first column
 *   flush_wtime=<wt>    flush output file every 'wt' seconds
 *   n_buf_steps=<n>     write output to file every 'n' output steps
 *
 * parameters:
 *   name           <-- base output case name.
 *   options        <-- whitespace separated, lowercase options list
 *   time_dependecy <-- indicates if and how meshes will change with time
 *   comm           <-- associated MPI communicator.
 *
 * returns:
 *   pointer to opaque time plot writer structure.
