56e7606e9a improved consistency between solvers/integrators 
by providing the integrand function as a parameter to integrate
rather that at construction, thus allowing reuse of a configured integrator

e60e3de474 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.

of following internal storage. Internal order should be preferred when no
specific order is needed, because it will be more cache efficient.
