a9b1544a9f Add premake support to build pybullet, Windows and Linux tested, will enable Mac in next commit.
Expose inverse dynamics to Bullet shared memory API, through b3CalculateInverseDynamicsCommandInit and
b3GetStatusInverseDynamicsJointForces command/status. See PhysicsClientExeample or pybullet for usage.
Add option for Windows and Linux to set python_lib_dir and python_include_dir for premake and --enable_pybullet option
Expose inverse dynamics to pybullet: [force] = p.calculateInverseDynamics(objectIndex,[q],[qdot],[acc])
Thanks to Jeff Bingham for the suggestion.

c28cd03fbd OpenVR controller can pick/drag objects. Instructions, Windows only:
Compile using premake+visual studio, and compile App_SharedMemoryPhysics_VR
Compile pybullet using cmake using cmake -DBUILD_PYBULLET=OFF -DCMAKE_BUILD_TYPE=Release ..
Create a symbolic link from c:\python\dlls\pybullet.pyd to C:\develop\bullet3\cmp\lib\Release\pybullet.dll
App_SharedMemoryPhysics_VR
Run Python. Here are some Python lines to get going:
import pybullet as p
p.connect(p.SHARED_MEMORY)
p.loadURDF("cube.urdf")
p.setGravity(0,0,-10)
p.setRealTimeSimulation(1)

Allow real-time simulation in physics server, add pybullet command setRealTimeSimulation to control it
Mesh decimation (reduce number of triangles/vertices) using a Blender modifier for Kuka IIWA and Husky
Disabled the 'glFlush' commands in GLInstancingRenderer.
Add VR controller methods to examples\CommonInterfaces\CommonExampleInterface.h
Use the ANSI version in Windows file/string operations instead of unicode, hope this doesn't break builds.
