Compute Diffusion Tensor

[SamTov]

What feature would you like to see added? Allow for the computation of a diffusion tensor rather than simply the net coefficient.

Describe how this feature would improve the code It would allow for enhanced analysis of properties.

Describe how this feature would work/possible implementations One should be able to pass a tensor=True parameter to the self-diffusion coefficients and have the code return a tensor of coefficients for each direction combination.
