def hasArgument(self, num):

Check whether the user supplied a particular number of arguments.

:param num: the argument number to check. Arguments are indexed from 0,
            so asking for the 0th arg will check to see if the user supplied
            1 or more args.
:return: true if the user has supplied at least <num> + 1 arguments.
