[Bruno Chareyre <bruno.chareyre@xxxxxxxxxxx>]

Hi,
Let me point out the fix in Cell.hpp in this commit. For Jan mostly, or
perhaps other users of periodic boundary conditions.
An error through time integration is removed. Previously, a rigid body
rotation of the cell would change the forces when cellDist!=(0,0,0).
It is probably not visible in slow moving cells, i.e. with small velGrad*dt.

Bruno

  Log Message:
  -----------
  A more precise integration of contact forces in periodic deformations, using period size of the previous step for the relative velocity update
+ cache a (matrix x matrix)  product for performance (previously re-computed for each other interaction)
