Module phetch::ui

The UI is what drives the interactive phetch application: it spawns threads to fetch Gopher pages and download binary files, it manages the opened pages (Views), it asks the focused View to respond to user input, and it performs actions based on what the View returns - like opening a telnet client, or displaying an error on the status line.

The UI also directly responds to user input on its own, such as ctrl-q to quit the app or keyboard entry during an input prompt.

Finally, the UI is what prints to the screen - each View just renders its content to a String. The UI is what draws it.
