Pokemon Catch Simulator

Simple command line application, uses the most accurate Pokemon catch formula found on Bulbapedia.

Pokeball multipliers can be found at http://bulbapedia.bulbagarden.net/wiki/Pok%C3%A9_Ball and
Catch rates can be found at http://bulbapedia.bulbagarden.net/wiki/L...catch_rate

If you're gonna enter 255 as the ball multiplier, don't bother!

Does not work with Gen II's Heavy Balls or Safari Zone in Gen IV's bait and mud!
