Erwin Coumans cf9f022d39 [pybullet] getNumConstraints, getConstraintInfo APIs. 
[pybullet] updated pybullet_quickstartguide.pdf
Fail clearly (assert, return BT_INFINITY) if link index is out of range for btMultiBody methods localPosToWorld,worldPosToLocal,localDirToWorld,worldDirToLocal.
pybullet getConstraintInfo
