* Usage is as follows                              *
* java play #1 #2 -1 -2 -3 -4 -5 -6 -7             *
* the -'s are optional and are integers            *
* #1 is the number of rounds to deal               *
* #2 is the number of players                      *
* the -n's are optional and are two characters     *
*   that describe a card                           *
* -1 -2 are the pocket cards to test               *
* -3 -4 -5 are the flop                            *
* -6 is the turn                                   *
* -7 is the river                                  *
>**************************************************<
* The program deals a number of rounds using the   *
* cards given and tests how many times the given   *
* pocket wins.                                     *
>**************************************************<
* The difference between play.java and jplay.java  *
* is that jplay.java uses a deck with a joker.     *
