0326fa93a8 made some progress in saving and restoring the state during the simulation, with identical results. 
Option to de/serialize btPersistentContactManifolds and fix lossy conversion during btMultiBody de/serialization of base world transform
(serialize the quaternion, not the converted 3x3 matrix)
There are still several caches not taken into account, and btMultiBody links/constraints are not deserialized yet etc.
See examples\pybullet\examples\saveRestoreState.py for an example.

e6e3da11e5 Implement true implicit friction cone, instead of friction pyramid, for btMultiBody vs btMultiBody and btMultiBody vs btRigidBody 
See data/sphere_small_zeroinertia.urdf for an example.

cb23e6c102 Fix pybullet.calculateInverseDynamics in the case where #dof != #joints (fixed joints). We still don't handle spherical joints in pybullet (even though the underlying inverse dynamics and forward dynamics support it) 
Also, add a inverse_dynamics.py example, with URDF files. Thanks to Michiel Lutter for the report and repro case!
This fixes issue #1379 https://github.com/bulletphysics/bullet3/issues/1379

eb97e06280 fix minitaur.urdf: move lower-leg inertia to center, add missing collision for one of the motors, add contact parameters for friction_anchor, spinning friction, compliance (stiffness/damping) 
fix in indexing for maximal coordinates (unused by default, still experimental, requires many iterations for Minitaur due to extreme mass-ratio, hence use of reduces/generalized coordinates)
modify quadruped.py to test maximal coordinates
wrap angular servo (positional) target within [-PI,PI] in btGeneric6DofSpring2Constraint
add 'j' key to show body frames in wireframe/debug mode
