==============================================================================
Test 1: With multiple elastic moduli but only prefactor has multiple values
==============================================================================
==> snippet from prm:
 	
 subsection Visco Plastic

    set Prefactors for dislocation creep          = 0.5e-18, 0.5e-18, 0.5e-18, 0.5e-18, 0.5e-24
    set Stress exponents for dislocation creep    = 1.0
    set Activation energies for dislocation creep = 0.0
    set Activation volumes for dislocation creep  = 0.0

 	set Elastic shear moduli   = 1.0e11, 1.0e11, 1.0e11, 1.0e11, 1.0e10
 	
 	
===> This runs without any problem 	


==============================================================================
Test 2: With only one elastic moduli, but multiple pre-factors
==============================================================================
==> snippet from prm:

  subsection Visco Plastic

    set Prefactors for dislocation creep          = 0.5e-18, 0.5e-18, 0.5e-18, 0.5e-18, 0.5e-24
    set Stress exponents for dislocation creep    = 1.0
    set Activation energies for dislocation creep = 0.0
    set Activation volumes for dislocation creep  = 0.0

 	set Elastic shear moduli   = 1.0e11     #, 1.0e11, 1.0e11, 1.0e11, 1.0e10



===> This run aborts in Stokes solve of first time step...here's the output....
