erwin.coumans a522cb98d9 Added a first version of FractureDemo, showing basic fracture and glue of rigid bodies. 
It assumes a btCompoundShaps (where the childshapes are the pre-fractured pieces)
The btFractureBody is a class derived from btRigidBody, dealing with the collision impacts and connectivity/propagating the fracture.
Press the F key to toggle between fracture and glue mode
This is preliminary work, can be used as a starting point to implement your own fracture.
