Softbody Documentation

[JamesH]

I've not looked at Bullet for a while and decided to update a game engine integration to the latest release, I've been experimenting with the Softbody integration and have a few questions.

• The main is about btSoftBody::Config, with brute force, trial and error I eventually got the softbody physics to work, but is there any more documentation on this ?
• I found that some settings had a profound effect on FPS (almost dropping me down to single figures), but I'd also like to know are there any best practices ?

Cheers
