Make output more readable

Currently output is hard to read as it is essentially a wall of text. Here are some things we could do to make it more readable in interactive mode:

- [ ] Clear the screen on each user keypress with `print(colorama.ansi.clear_screen())` (potentially make it optional since some users may want to scroll backwards.
- [ ] Colorize the request for user interaction in order to differentiate it (perhaps grey)
- [ ] Colorize code blocks, ideally this will be syntax colored but event changing the background and font colour will help
- [ ] Colorize headings
- [ ] Colorize output vs documentation
- [ ] ???
