"""
paren_tester.py
The paren_tester program imports a student's paren_checker.py program which 
defines a function isValid(string). That function takes a string of 
parentheses as a parameter and returns True if the parentheses are "well-formed",
and False otherwise.

The paren_checker.py program should use a Stack object to check the parentheses.
