Detailed Description

Simple library for doing things involving moving the curser when producing terminal output.

This is achieved using ANSI escape codes, see:

https://en.wikipedia.org/wiki/ANSI_escape_code#CSIsection

That page is hard to decipher. Suffice to say that the left-hand-side of the table for "CSI introducers" is interpreted as follows:

\033[ n A - move curser n places up. \033[ n B - move curser n places down.

... and so on. Colours are then the "Set Graphic Rendition" part that appears as "CSI n m" and translates to ""\033[ n m".
