//! Simple Text Output Protocol
//!
//! The simple-text-output protocol provides a simple way to print text on screen. It is modeled
//! around the old VGA-consoles, but does not carry all the old cruft. It expects a rectangular
//! text array and allows you to move the cursor around to write Unicode symbols to screen.
