@hackage rungekutta21.0.3

This package contains a collection of explicit Runge-Kutta methods of various orders, some with fixed-size steps (no error estimate) and some intended for adaptive stepsize (ie, they include an error estimate). There are a couple of test programs which include some adaptive stepsize control, however there is not yet any such routine in the library itself.

This package started as a fork of 'rungekutta-1.0.2' (which had been dormant since 2009), with proper documentation and modern project structure.
