[Developers] Running ADMB with separate exe and data dirs

[Hans Julius Skaug]

Ben and Dave,

I agree that adopting the lme4 specification for random effects
would be the best way. Any idea about how to learn that technology?

The other featurs Dave asks for should in my opinion be dealt
with as a hard coded library of variance functions. These
can invoked by an argument to the R function.  This is not a very elegant 
solution  but it is simple and robust. Mixtures
is also a generic feature that can be applied to all kind of models.
