Dynamic Step Size Support

[teubert]

Support for dynamic step size (i.e., step size decreasing or increasing with time).

For example: You could have a small step size as you approach an event, or you could have a small one in the near future, increasing with time.

Potential approach: allow for supplying function step_size(t, x) -> dt
