Exact -- the program that finds what answers really are.

I wrote this program because I was mad that the TI92's could do stuff and
give back exact results.  I am talking about giving back answers like 2
(square root of two) or 3pi/7.  This program will take the number
stored in Ans and try to find what the exact number is.

Explanation of the menu:
Norm is for normal numbers.  By normal I mean no pi, e^, or ln's.
const is like norm but with a constant.  This could be pi, or e, or g (gravity)
      or whatever.  Or, you could type in a number.
ln is for numbers that are the natural log of something.
e^ are for numbers that are the exponential of something.

The program might take a few seconds to find an answer.  It starts by looking
at the smallest numbers first, and then goes to the larger numbers.  This
progam might not find answers either.  If a number is out of its range it
won't get it.  Sometimes, it might not give simplified form of an answer.
The only example that I can think of is giving 8 instead of 22.  it is
the same number, just not the right form.  I think I fixed this problem, but
I am not sure.

I suppose I should say that I got the idea for this program from a copy of
Eightysomething!, TI's newsletter for teachers.  I tried to use a program
that they had for a TI82, but it was slow.  I rewrote it to be twice as fast.
(I timed it.)  Then I added new features.  The result is what you have here.

If you have any suggestions on how to improve this program, send me some email
I am always looking for ways to make my programs better.
