## Code
We start by setting up our environment by ensuring some sane values for both `$` and `window`,
enabling EMCAScript 5 strict mode and overwriting console to prepend the name of the class.
(($, window) ->
"use strict";
console =
log: (message) ->
window.console.log "[be.bastelstu.Chat] #{message}"
warn: (message) ->
window.console.warn "[be.bastelstu.Chat] #{message}"
error: (message) ->
window.console.error "[be.bastelstu.Chat] #{message}"
Continue with defining the needed variables. All variables are local to our closure and will be
exposed by a function if necessary.

When **Tims Chat** becomes focused mark the chat as active and remove the number of new messages from the title.

When **Tims Chat** loses the focus mark the chat as inactive.
