There are breaking changes in this release. Sorry, but this is closer to the final structure and close to complete.
* OpenSign and OpenSignCanvas are now two separate files
* New scroll_from_to() handles all the scrolling logic
* All scroll functions now just use scroll_from_to() under the hood for reduced code
* Removed sleep() function
To install in CPython, `sudo pip3 install opensign`.
Read the [docs](https://opensign.readthedocs.io/en/latest/) for info on how to use it.
