version 0.2a finally released

Hi to all my 20 unknown users!

The alpha version is finally released. Sorry for being late after promising to release - I was busy at my (paid) work (Intel).

The alpha release has a GUI, but I disabled the support for dimentions over 3.

p.s - If you're downloading\using my code PLEASE drop me an e-mail to g_diskin@(sf users) I really want to know what are you using this code for (researching stability properties, simulations, base code for your simulators, example code, learning vpython, something else?)
