Support for additional numerical methods

[jordissm]

In addition to the Runge-Kutta method, it is advised to have support for additional numerical methods. Especially, symplectic integrators such as Leapfrog should be considered as they conserve energy.

Do you have a reference for the algorithm?

Standard references should be good enough:

On the method itself:

• Wikipedia
• Lecture at University of California, Santa-Cruz
• Feynman Lectures on Physics, Vol. 1 - Sec. 9.6

On the C++ implementation:
