Thanks everyone for positive comments :)

I rewrote the Bridge script. No new functions at the moment, but internal logic has been changed. This is a first step to bended bridges.
Also I wrote a script for polygon splitting. As Bridge it's very simple right now.
I decided to write all subdTools scripts with basic functionality, and only after that I'll start to improve them.
