Ok. Does it fix the SDECLink problem?
TriaxialTest.cpp was also using elasticContactLaw and 
elasticCohesiveContactLaw at the same time, I don't know if you or me 
commited that but I reverted that and will commit soon : TriaxialTest is 
not supposed to be cohesive + 2 simultaneous contact laws makes no sense.

I think the value of stress and strain after X iterations + the peak 
stress value would make good tests. If they don't change you can be sure 
that the physics and mathematics in Yade were not affected, because they 
result from very complex processes, highly sensitive to initial 
conditions (Lorentz sort of).

The only thing is we need to swith from random positioning to a text 
file, I still have to create this file and to get the code for loading 
positions back.
