Java Gear Generator: Involute and Fillet

I have been working on making gears lately and found the process harder than it should have been. I found some parametric equations for a 1/2 tooth involute and fillet profile here (http://eng-tips.com/viewthread.cfm?qid=272852&page=5) and whipped up a Java program to generate points in either a tab delimited csv format or an ibl format for those of us using CAD software. Gears can be generated in metric or standard.

EDIT: I updated the code to support profile shifting for gears with small numbers of teeth, as well as more descriptive prompts. Also uploaded sample output files for a 32 pitch, 20 degree, 32 tooth gear.
