Switched material status for slave gauss points in twofluid material.
Renamed giveLength() to computeLength() so that the base class function in Element is overloaded instead of creating a duplicate function. Renamed "RealStress" to "GeneralizedStress" for the generalized stress vectors.
Fixed typo in renamed function.
Correcting a few includes.
Fixing accidental modification in earlier commit.
Generalized updateSharedDofManagers to work with arbitrary UnknownNumberingScheme instead of having 2 hardcoded cases.
Added missing zero'ing of variable.
Increased tolerance in test to allow for small errors in numerical integration.
Merge branch 'master' of github.com:Micket/oofem into ThroughThicknessCrack
