Integrate an initial value problem using 4th order Runge-Kutta method.
This is a concrete sub-class of vtkInitialValueProblemSolver. It uses a 4th order Runge-Kutta method to obtain the values of a set of functions at the next time step.

Given initial values, xprev , initial time, t and a requested time interval, delT calculate values of x at t+delT (xnext). delTActual is always equal to delT. Since this class can not provide an estimate for the error error is set to 0. maxStep, minStep and maxError are unused. This method returns an error code representing the nature of the failure: OutOfDomain = 1, NotInitialized = 2, UnexpectedValue = 3
