Add concrete Fatras hit type
- Adds a concrete
ActsFatras::Hittype. - Streamline
ActsFatras::Interactorby always using the concrete event data types and removing many unnecessary template arguments, e.g. particle and hit type and the separate hit creator. - Add
ActsFatras::Interactorunit tests by using mock ups for the propagator and stepper inputs. - Fixes the
ActsFatras::Interactorto always correct the material for non-zero incidence.
Fixes #695 (closed) and #696 (closed).
