It could be useful to have a simple integrator as a check.
Feel free to work on it independently, following the GSL design
document and existing GSL integration api, and post your progress on
this list. e.g. url for the source. It should be possible initially
to write it as a single file which can be dropped into any application
as an add-on to GSL.
If there's favorable feedback we can see about putting it in GSL when
it is stable and fully-tested.
