* Card Example -- test3.py file *
*********************************

Trace table not shown.

The test3.py file uses double for loop to append Card objects to the cards array in this order:
2C 3C ... JC QC KC AC 2D 3D ... JD QD KD AD 2H 3H ... JH QH KH AH 2S 3S ... JS QS KS AS

Then the cards are randomly shuffled.  Here is the output:
2C 3C 4C 5C 6C 7C 8C 9C 10C JC QC KC AC 2D 3D 4D 5D 6D 7D 8D 9D 10D JD QD KD AD 
2H 3H 4H 5H 6H 7H 8H 9H 10H JH QH KH AH 2S 3S 4S 5S 6S 7S 8S 9S 10S JS QS KS AS 

9H 3D KS 4C KC 7C QC 6C JD 10D 6S 9S JC 2C 8S AH 8D QH 8C AS JH 5S 10H 3H 6D 10C
