* @property {String} className - An optional additional className for the button.
* @property {String} description - The value that will display as a tooltip and in
* the options panel for enabling/disabling.
* @property {Function} onClick - The function to run when the button is activated by
* click or keyboard shortcut. First argument will be the 'click'
* event, and second argument is the toolbox instance.
* @property {Boolean} isInStartContainer - Buttons can either be placed at the start
* of the toolbar, or at the end.
* @property {Function} setup - Function run immediately to listen for events changing
* whenever the button is checked or unchecked. The toolbox object
* is passed as first argument and a callback is passed as second
* argument, to be called whenever the checked state changes.
* @property {Function} teardown - Function run on toolbox close to let a chance to
* unregister listeners set when `setup` was called and avoid
* memory leaks. The same arguments than `setup` function are
* passed to `teardown`.
* @property {Function} isTargetSupported - Function to automatically enable/disable
* the button based on the target. If the target don't support
* the button feature, this method should return false.
* @property {Function} isChecked - Optional function called to known if the button
* is toggled or not. The function should return true when
* the button should be displayed as toggled on.
