Branch ODE

I've opened a branch on github to start implementing an ODE solver
framework. Right now I am targetting implementation of something
equivalent to odeint-v2 ( https://github.com/headmyshoulder/odeint-v2 ).

I'm not pushing to master until I get this properly sorted out, the
method names are going to be in flux, much of the implementation details
are likely to be very unstable, and I want it to be a little cleaner
before I let it out in the wild.

In the meantime, I believe the branch is visible if there are immediate
comments. Much of what's done to now involves a class hierarchy skeleton
and copy-paste of the documentation from odeint. As the classes mature,
I will bring the documentation closer to the smalltalk version.

Great work Dan !
Could you push this branch on the master repo also, so I could
experiment a little bit ?
Do you want to do some remote pair programming from time to time ?

Hi! I'm student on Google Summery of Code.
I wrote explicit second order Adams-Bashforth, Heun's methods and
implicit first order: Backward Euler, second order: Midpoint, Trapezoid, backward differentiation formula (BDF) methods. Also I wrote tests for methods.
I try to use existing disign.

Hello.

I wrote backward differentiation formula (BDF) and the Adams–Bashforth method (AB) for orders 2, 3, 4. They are implicit and explicit linear multistep methods.
Now I want write Adams–Moulton method for orders 3, 4 ( second order A-M method is the trapezoidal rule) and then start with benchmarks.

Best regards,
Natalia.
