Title:
  Sign convention in TriaxialStressController not consistent ?

Status in Yet Another Dynamic Engine:
  New

Bug description:
  Hi,

  When used as stress or strain rates, sign convention of "goal1/2/3"
  attributes of TriaxialStressController engine seem to me as not
  consistent.

  Positive values for stress goals correspond indeed to compression, whereas positive values for goal strain rates involve extension.
  Which is itself not consistent with TriaxialStressController.strain variable (in the end, to obtain positive TriaxialStressController.strain, you need to set negative strain rates goal variables).

  Not difficult to fix, but maybe require a common decision. (I vote
  myself for geomechanics convention)
