openscad parameterizable tank tracks

This is an easy to print parameterizable tank track library.

Create your custom tank threads the way you want.
I made this because there was nothing quite suitable for my tank.
This library also generates the track wheels and hubs (with axle mount).

Sadly I did not have the time yet to document this fully, so if you need some help with the parameters, please feel free to ask.

An demo has been included in the file to show what is possble.
