non fitting or derived parameters in models (Trac #944)

[RichardHeenan]

Would be good to have a new type of parameter in models that is not itself allowed to be fitted. This could for example specify the number of points or convergence criterion to be used in an integration scheme for P(Q), if possible to return the last computed value of a derived parameter such as Debye length, or provide the value of a fixed constant used in the model calculation.
