Console Traits

Contains a trait which describes a console. A console is a rectangular monospaced text display, of a certain width and height. You can write Unicode text to it.

Currently we assume UNIX LF sematics - that is a sole LF implies a new line and carriage return (as distinct to Windows semantics where you would need to send a CRLF pair).

Implementors should handle the following Unicode characters specially:

• 0x08 (BS) - Backspaces one character (and erases it)
• 0x09 (TAB) - Move to next tab stop, or the end of the line if no tab stops left.
• 0x0A (LF) - Line feed.
• 0x0D (CR) - Carriage return.
• 0x7F (DEL) - Ignored.
