/**
 * Define text editors, such as WYSIWYGs or toolbars to assist with text input.
 *
 * Text editors are bound to an individual text format. When a format is
 * activated in a 'text_format' element, the text editor associated with the
 * format should be activated on the text area.
 *
 * @return array
 *   An associative array of editors, whose keys are internal editor names,
 *   which should be unique and therefore prefixed with the name of the module.
 *   Each value is an associative array describing the editor, with the
 *   following elements (all are optional except as noted):
 *   - title: (required) A human readable name for the editor.
 *   - settings callback: The name of a function that returns configuration
 *     form elements for the editor. See hook_editor_EDITOR_settings() for
 *     details.
 *   - default settings: An associative array containing default settings for
 *     the editor, to be applied when the editor has not been configured yet.
 *   - js settings callback: The name of a function that returns configuration
 *     options that should be added to the page via JavaScript for use on the
 *     client side. See hook_editor_EDITOR_js_settings() for details.
