Detailed Description

Runge-Kutta-Fehlberg method.

This is a semi adaptive implementation of rkf - the interval only shrinks. As a result interval calculations remain trivial, but sometimes too many calculations are performed. Rationale: this code is not meant to be a universal pain-reliever for ode's. Rather it provides some safety if the number of intervals is set too low, or the problem function behaves a bit nasty in rare conditions.
