[feature] Make odeint works with std::tuple and boost::units

[pierre blavy <blavy@…>]

Dear developper, here is a patch that

• make odeint work with std::tuple.
• make odeint work with boost::units tuple.
• patch std::numeric limits for boost::units::qunatity, by delegating limits to the underlying type. That's important as, without this patch, std::numeric_limits silently return stupid values with boost::units::quantity.

I'm not a boost developper and I realy had trouble to understand the documentation, so I'm not sure that the things I've done are correct or doens't break an other part of boost, so please, carefully review this code. I post it in the hope that it will be usefull for you.

make odeint work with std::tuple

Hi,

sorry for the very late reply. I think boost::tuple and std::tuple should already work with the fusion_algebra. This algebra is intended to work with heterogeneous containers like boost::fusion::vector<>, boost::tuple<>, std::tuple<> . Maybe one needs to specialize the fusion_algebra_dispatcher to work with with boost::tuple and std::tuple but in principle it should work. I will try to write a minimal example with std::tuple.
