returns a pylist of contact points. Each point has the following data:

	0     int m_contactFlags;//unused for now

         2     int m_bodyUniqueIdB;

         8-9-10     double m_positionOnBInWS[3];//contact point location on object A, in world space coordinates
         11-12-13     double m_contactNormalOnBInWS[3];//the separating contact normal, pointing from object B towards object A
         14     double m_contactDistance;//negative number is penetration, positive is distance.

1c65cae6d0 [SharedMemory] Calculate inverse dynamics now uses world gravity. 
Small change that takes the world gravity and applies it to the
body during the call to inverse dynamics in the shared memory
interface. Otherwise the gravity vector is left at the default
value and there is currently no interface to set the gravity
for the inverse dynamics system.

4094b9f0df Disable 'm_robotSim.setNumSimulationSubSteps' because it is not needed at the moment 
Fix issue in contact/friction between btMultibody and btRigidBody (external force/torque of btRigidBody was not taken into account during contact/friction setup)
Allow 0.1 mm slop in contact, to avoid loosing contact. Todo: allow contacts with positive distance in multibody solver.
