[Developers] Need for simpler way to describe the kind of simple mixed models most people are used to.

[dave fournier]

I was thinking about contrasts for fixed effects.
thge point is to create a "contrast" object such as

   contrast a_contrast(1,n)

so that in the SEPARABLE_FUNCTION call for the i'th observation
you can simply pass

   a_contrast(i)

to the separable function where i is the category index value.
That makes it simpler to parse a CSV file for the data and create code
automatically based on an R like specification of the mixed model.

Right now you can't do that because the parameters of a_contrast are
not independent variables.
