Detailed Description

This class implements associated Material Status to MPlasticMaterial. It is attribute of matStatusDictionary at every GaussPoint, for which this material is active.

Idea used there is that we have variables describing:

1. state at previous equilibrium state (variables without temp)
2. state during searching new equilibrium (variables with temp) when we start search new state from previous equilibrium one we copy non-temp variables into temp ones. And after we reach new equilibrium (now described by temp variables) we copy temp-var into non-temp ones (see function updateYourself).
