Crow v2.0.0

This update to Crow contains a huge number of internal changes related to the core organization and environment of the tool.

• Core functions have been subdivided into easily maintainable, modular files
• Testing has been added with 100% code coverage
• The base UI is gone, and Crow now directly launches to the UI
• Online documentation page added through GitHub.io
• GitHub actions added to keep docs up to date, tests running, and code well formatted

Hopefully, these changes make Crow much easier to maintain in the future.

What's Changed

• Major Restructuring of Crow by @JacksonBurns in #15
