[ADMB Users] diagnostics to help (especially new) users

[dave fournier]

I am working with a guy who has tried to produce a fairly complex model
without understanding much about how ADMB works. One of the problems that
newbies have is the nature of properly initializing variables.
It should be easy to have a

    ./xxx   -init

to verify that parameters are properly initialized.  It would just have to
evaluate the userfunction twice with the same initial parameter values and
check the values of the model parameters to see where they differ.
