Nice work. Note @rveltz that this actually requires a DiffEqBase tag, but it's already to merge earlier since instead of throwing a warning on an ignored keyword argument, pre-tag it will throw an error. We chose to go with warnings because technically the solution is still correct, but the user should know that some of what they think might be tweaked isn't actually tweaked. This is a clean solution that handles all of the keyword args.

OK, dtmin/dtmax added
