Subject: 	Calc-TI - gamma function for ti-92

Here is a TI-92 function to compute values of the gamma function (if you
don't know what that is ... look it up).

I gave this function the name (capital greek gamma) on my calculator ---
that is, [2nd] [G] [shift]-[G].

It computes exact values (using factorials) for gamma(n), n an integer (it
even reports "infinity" for non-positive integers). It also reports exact
values for fractions with denominator 2.  For other values, it uses a
numerical method taken from "An Atlas of Functions" by Spanier and Oldham.

Note: this function is "list-enabled" --- that is:
  [Gamma]({2,3,1/2})
returns the list
  {1, 2, sqrt(pi)}.
