hints for windows users

you have to install latest version of scipy and numpy (SVN version) and matplotlib.

If you get some erro messages try comentting the line that says:
import uncertaintyMiniFrame
on wxframe1.py

I'll have a bug fix release out soon. I am also considering releasing a fat Binary Version without dependencies.

good luck,

Flavio

So I have uploaded an Examples.zip file with some example models for you to try out.
