** Name: 

** Filename: PseudoRandomDrv.cpp

** Project #: Data Structures And Other Objects Using C++ 2nd Edition
              (Micheal Main & Walter Savich)
              <Pg. 89 Programming Project #11>
              

** Project Description: Design and implement a class that
   can generate a pseudorandom sequence. Perform test of
   the class for working results

** Output: A user defined length for pseudorandom sequence 
           of numbers 

** Input:  Input the number of times to test PseudoRandom
           class. 

** Algorithm: Design PseudoRandom class with two functions.
                 function Init to initialize the first of the
		 pseudorandom numbers.
		 function NextNum to return the next number 
		 that becomes the seed to create next random
		 number.
              Design driver PseudoRandomDrv to test class 
		 Pseudorandom.
