module Vedeu
module Cells
# 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.)
