Changed
- Functions for ascents and descents now take an optional argument to specify what step size to calculate.
- Moved sorting functions from `permuta/bisc/perm_properties.py` to `permuta/patterns/perm.py`.
- If you pass an iterable (that is not a perm) to a contains method, then it will now raise an error.
These should be passed with the splat '*'.
