Overview

This class is part of a private API. You should avoid using this class if possible, as it may be removed or be changed in the future.

Provides the character/escape sequence to draw one cell of a with a custom value, colour and style.

The Vedeu::Cells::Escape object represents an escape sequence as a single character, meaning they will behave dependent on the context in which they are used.

(In a terminal, an escape sequence makes sense, when a view is being rendered as HTML, the sequence may be meaningless, for example; the sequence to show or hide the cursor.)
