/**
 * ## Datetimepicker Widget
 *
 * This widget will convert itself or multiple elements into datetimepicker instances. Check the defaults object for a
 * list of available options.
 *
 * You can also set this module in a container element and provide the "data-datetimepicker-container" attribute and
 * this plugin will initialize all the child elements that have the "datetimepicker" class into datetimepicker widgets.
 *
 * jQuery Datetimepicker Website: {@link http://xdsoft.net/jqplugins/datetimepicker}
 * 
 * ### Options
 *
 * In addition to the options stated below, you could also add many more options shown in the
 * jQuery Datetimepicker documentation.
 *
 * **Format | `data-datetimepicker-format` | String | Optional**
 *
 * Provide the default date format. If no value is provided, the default format will be set
 * to `'d.m.Y H:i'`.
 *
 * **Lang | `data-datetimepicker-lang` | String | Optional**
 *
 * Provide the default language code. If the current language is set to english, the default
 * language code will be set to `'en-GB'`, else the language code will be set to `'de'`.
 *
 * ### Examples

 * <input type="text" placeholder="##.##.#### ##:##" data-gx-widget="datetimepicker" />
