+Currently only an interface to the Runge-Kutta methods:

+The interface is almost certainly going to change. Sundials gives a
+rich set of "combinators" for controlling the solution of your problem
+and reporting on how it performed. The idea is to initially mimic
+hmatrix-gsl and add extra, richer functions but ultimately upgrade the
+whole interface both for sundials and for gsl.
