/*
* MCS 141
* HW 7
* a program that uses the RolloverCounter class to test its functionality
* You don't need to change anything in the program...it is just here to help you test your code in the RolloverCounter
*
When this program is run the output should be:
*************************************************
creating new counters...
creating counter c1 with max value = 5...
creating counter c2 with max value = 3...
creating counter c3 with max value = -2 (this should not work)...
Error creating counter: java.lang.RuntimeException: invalid maximum value

incrementing the counts 10 times and printing counts...
c1: 1 c2: 1
c1: 2 c2: 2
c1: 3 c2: 3
c1: 4 c2: 0
c1: 5 c2: 1
c1: 0 c2: 2
c1: 1 c2: 3
c1: 2 c2: 0
c1: 3 c2: 1
c1: 4 c2: 2

decrementing the counts 7 times and printint counts...
c1: 3 c2: 1
c1: 2 c2: 0
c1: 1 c2: 3
c1: 0 c2: 2
c1: 5 c2: 1
