 * Initialize FVM to Catalyst object writer.

 * Options are:
 *   private_comm        use private MPI communicator (default: false)
 *   names=<fmt>         use same naming rules as <fmt> format
 *                       (default: ensight)
 *   input_name=<name>   define input name (default: writer name)
 *
 * 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.
