Added ProjectWorkingPath to FailureMechanismeParamatersMStab.Moved shared code for tests in both Common and Inwards to DamMacroStabilityTestHelper.Related to Issue [MWDAM-1056]
Adapted Interface for PostProcess to be able to handle multiple results instead of just one. This is required for stability calculations as the model BishopUpliftVan requires two calculations and three results (1 per calculation, one overall result). Also added extra file name for the second model to be able to support two calculations.Related to Issue [MWDAM-1057]
Added iterationIndex as parameter to Prepare() Interface in order to be able to set correct file names in case of design. Implemented setting correct name for sti-file to be used in the calculation by Stability Outwards. Related to Issue [MWDAM-1057]
