* Assignment: Project 6: Sets 
***********************************************
* main.cpp should get the user input for the
* two sets (you may want to use the strtok 
* function).  It should two create two pointers 
* to Set objects (using "new") to hold the values.  
* It should add elements to each set, print the 
* sets, and then ask the user whether to find the 
* union or intersection between the sets.  It 
* should print the result of the union or 
* intersection, and then release the space for 
* the objects.
