[ADMB Users] restricted maximum likelihood

I used the definition in Pinheiro and Bates on page 75.

Interestingly I have seen Bates opine that  reml makes no sense for
nonlinear mixed effects models. But that usually means that he just
can't get something to work with inferior techniques (That is the usual
R experts' approach to anything that can't be done in R).

Personally I like to implement the estimation procedure and then
evaluate its performance on simulated and real data rather than entering
into theological discussions.
