If all processors pass NULL arguments for the import arrays, the value of <i>num_import</i> should be -1.
<p>
Similarly, if import lists are provided, 
non-NULL values for input arguments <i>export_global_ids</i>, <i>export_local_ids</i>, <i>export_procs</i>, and <i>export_to_part</i> are optional.  
The values must be non-NULL only if no import lists are provided or if 
the export lists are used by the application callback functions
