Make output more readable

[rgardler-msft]

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
• [ ] ???
