/**
 * Creates an instance of sceditor on all textareas
 * matched by the jQuery selector.
 *
 * If options is set to "state" it will return bool value
 * indicating if the editor has been initialised on the
 * matched textarea(s). If there is only one textarea
 * it will return the bool value for that textarea.
 * If more than one textarea is matched it will
 * return an array of bool values for each textarea.
 *
 * If options is set to "instance" it will return the
 * current editor instance for the textarea(s). Like the
 * state option, if only one textarea is matched this will
 * return just the instance for that textarea. If more than
 * one textarea is matched it will return an array of
 * instances each textarea.
 *
 * @param  {Object|string} [options] Should either be an Object of options or
