Added initial Smoothed Particle Hydrodynamics implementation (SPH), for CPU and CUDA.

This software is contributed under the ZLib license by Rama Hoetzlein, http://www.rchoetzlein.com We plan to integrate the SPH into the core Bullet library, including interaction with rigid bodies and soft bodies.
