/**
 *  <i class="fa fa-hand-o-right" aria-hidden="true"></i> [See All Options](#method_validate)
 *
 *  Validate over a date range. Uses the native Date and Intl APIs. Will parse strings using `new Date(<string>)`,
 *  so care must be taken to ensure you use only ISO 8601 strings if you want cross-browser compatibility.
 *
 * ## Examples
 *
 * To set `before`, `onOrBefore`, `after`, or `onOrAfter` to the current instant, use a JS getter:
 *
 *  ```javascript
 *  validator('date', {
 *    get after(): { return Date.now(); },
 *    before: '2020/01/01T00:00:00.0000Z', // Must be ISO or Date!
 *  })
 *  ```
 *
 *  @class Date
 *  @module Validators
 *  @extends Base
