Title: Adding multi-tensor simulation 

Hi all, I have added a multi-tensor based simulation of the diffusion signal. It can be called in the same way as we call the SticksandBall simulation with the difference that the diffusivity value is replaced with the an array with the eigenvalues of each tensor (in each row).
