 * The classic hello world program, with a twist - prints a message
 * from the command line at every Place. 
 * The messages from each Place may appear in any order, but the
 * finish ensures that the last message printed will be "Goodbye"
 * Typical output:
 * [dgrove@linchen samples]$ ./HelloWholeWorld 'best wishes'
 * Place(1) says hello and best wishes
 * Place(2) says hello and best wishes
 * Place(3) says hello and best wishes
 * Place(0) says hello and best wishes
 * Goodbye 
 * [dgrove@linchen samples]$
