/* Code Beauty Pageant!
 *
 * Write a class that represents a stopwatch.  You can design this however you'd like.
 * We'll vote on the prettiest interface (i.e. the interface that's easiest to read and
 * use).  You don't need to be clever with the implementation - in fact, you don't
 * even have to have one - but you should have the best interface you can.
