 * An abstract service for parsing and formatting dates for the

 * Converts between the internal `NgbDateStruct` model presentation and a `string` that is displayed in the
 * input element.
 *
 * When user types something in the input this service attempts to parse it into a `NgbDateStruct` object.
 * And vice versa, when users selects a date in the calendar with the mouse, it must be displayed as a `string`
 * in the input.
 *
 * Default implementation uses the ISO 8601 format, but you can provide another implementation via DI
 * to use an alternative string format or a custom parsing logic.
 *
 * See the [date format overview](#/components/datepicker/overview#date-model) for more details.
