A grab bag of better ranges for Python projects.

Yup, but it is small.

pip install setr

1. Allow MultiRange not to need to sort after ever addition.

• A function that requires sorting should check a boolean value and sort if nec.

2. Create an iter for MultiRange.
3. Create BigRange.
4. Allow the use of steps.
5. Think about implementing a __sum__.
6. Add examples in this README.
