Chuyuan Fu 7aba1f9e8a Use two SI solvers as blocks in block solver. 
In the btBlockSolver we are experimenting with, we have SI for both multibody and rigid body. I'm currently replacing rigid body SI solver with two smaller SI solvers. The two examples provided by RigidBodyBoxes.h should have the same behavior.
