Checkbox

[jamesplease]

Todo

Refactors

• Emify
• Update fill animation to use a circle
• Confirm that CSS cannot get any lower specificity. There are quite a few > 1 specificity selectors in this thing

New Things

• Add disabled state
  • Checked
  • Unchecked
• Confirm that callback props like onX work as expected (I don't think that they do atm)
• Focus state. Keyboard input works but there is no indicator when the checkbox is focused

Docs

• Add docs to the website

This is a part of #64
