Name: debugSetter
Description: Set the debug mode to on or off based on command line argument.
Algorithm: Set debug off by default and use a while loop to determine if
commands line argument exists to turn it on. Otherwise, it is
automatically off.
Parameters: arg1: default argument 1 from main
arg2: default argument 2 from main
Output: void
Result: Debug is either enabled or disabled during execution.
