Notes
This routine encodes the design of fourth order Rosenbrock methods as described in Hairer and Wanner volume 2.
It is used here to implement several methods from the book and can be used to experiment with new methods.
It was written this way instead of by copying coefficients in order to provide better than double precision satisfaction of the order conditions.
