TriSolve92 0.1alpha release [1/1]

I thought that i would release the alpha version of my new
triange-solving program for the TI-92.  Although I call it an alpha, it
could probably be considered a beta; i'm pretty sure that it is
completely functional/accurate, but its still too large and too slow...

Anyways mail suggestions or complaints to JPMcClain@colint.com
