I know that it doesn't work 100% with the map*** methods that shouldn't be used with a sparse vector. I'll clean those up shortly (including uncommenting unit tests). Just want to get more eyes on this for the methods that matter.

Added a new minimization package with an implementation of the Brent algorithm

contributed by Gilles Sadowski.
The implementation needs some testing as it seems to never use the parabola fitting
and only relying on golden section. This may be due to the refactoring I did on
the original patch.
