turbulenceModels/laminar/Giesekus: Giesekus model for visco-elasticity

Browse Source 
Implementation of the Giesekus model for visco-elasticity, derived from the new
generalised form of the Maxwell model which now support additional sources.

    Giesekus, H., 1982.
    A simple constitutive equation for polymer fluids based on the
    concept of deformation-dependent tensional mobility.
    J. Non-Newton. Fluid. 11, 69–109.

This implementation is instantiated for incompressible, compressible and VoF
two-phase flow.
