 * Class Test24 is a unit test main program for classes {@linkplain

 * WorkerRegion}, and {@linkplain edu.rit.pj.WorkerIteration WorkerIteration}. A
 * worker iteration iterates over the strings given as command line arguments.
 * Each iteration prints the item (string) and the worker index processing that
 * item.
 * 

 * Usage: java [ -Dpj.np=Kp ] edu.rit.pj.test.Test24 strings
 * 
Kp = Number of parallel processes
 * 
strings = Strings to be iterated over
