RKCheck

RKCheck checks the order of a Runge-Kutta method. The method is specified in an xml file. All computations are exact; there is no approximation at all. Because of this, the application can handle only methods for which an exact representation of the coefficients exist. RKCheck currently supports integers, rational numbers and quadratic surds (i.e. numbers of the form (p1 + p2 sqrt(d)) / q), and only if all quadratic surds in one file share the same d.
