"Platform Boots"

This release will attempt to add continuous integration for Windows and Mac OS, with extended CI for Ubuntu "Bionic". Python 3.9 will be added as well. Test coverage shall be >= 90%. CI coverage will also include various combinations of dependency versions to determine true compatibility.

In using FlowKit, there are a few areas where the API can be improved to make repeated tasks more convenient, and a few features may be removed (anom events) or added (SampleCollection class).

For documentation, this means ensuring that all classes, methods, and functions have up-to-date docstrings. It will also include more tutorials demonstrating the FlowKit functionality, as well as a Frequently Asked Questions section. Finally, creating ReadTheDocs pages for everything from installation to usage.
