The timesteps in breve are controlled by the integrator, and are not
guaranteed to always be the same.  Instead, they can be chosen by the
integrator in order to minimize simulation error.

If you want to keep a consistent and exact count, you might want to
have your controller keep an iteration count.  In it's iterate method,
you would increment the value, and then provide a method that other
objects could use to retrieve the value.
