OptimResult return type #9

How do you feel about a default OptimResult return type for all minimizers? I was thinking about a struct that contains:

information about termination reason,
runtime,
number of function evaluations,
the gradient/hessian (if applicable),
the minimizing point and
the target function value

(this list is heavily inspired by scipy.optimize) More options can be added as more optimizers are coded.

I'm definitely not against. Currently it's not done just for simplicity reasons, but if users find that other outputs are also useful, it might be a nice thing.
