Details:

I wrote a small function performing a gridsearch on a function handle.

The benefit is mainly that one saves multiple nested loops, so code using this
function gains readability. Furthermore, in an utopian future that function
might be parallelised better than nested loops.

Another benefit is that one can get back all function evaluations, so an
detailed analysis of the results can be done. This is not possible with
fminsearch at the moment.

I would be glad for any criticism of that function. Furthermore I think that
it would be a good alternative to have either in Octave itself or in the optim
package.
