c Decode/copy parameters for this thorn into grid scalars
c so we can share this with friends
c so the Calc_Tmunu code in ../include/Scalar_CalcTmunu.inc
c can use them in computing the stress-energy tensor
c
c Actually we only have to copy those parameters which are
c used by the Calc_Tmunu code. For simplicity we decode
c exact_model into the integer decoded_exact_model, then
c copy only the per-model parameters for those models which
c have stress-energy tensor code in ../include/Scalar_CalcTmunu.inc .
