Class ooset was written for a C++ course that I'm taking.  The class is
used for algebraic sets such as { 1, 3, 8, 11 }.  It includes extensive
operator overloading.  Most C++ textbooks illustrate operator overloading
on a string class and the examples are limited to only a few operators.

Feel free to use the class if you wish.  Any comments or feedback would
be appreciated.

As with any problem, there are many solutions.  The code that my 
instructor handed out for this assignment is probably quicker or more
compact.  It's so compact that I'm still trying to decipher it.  I liked
my code better from a learning point of view, I and others can follow
it.
