improved for inserting profile timings from Python, to analyzer performance of pybullet programs.

See examples/pybullet/examples/profileTiming.py for an example. Note that python and c++ is properly interleaved.
Open a timings with a name, close the timing without a name. Note that timings can be recursive, added/popped as a stack.
