* @category Common Helpers
* @summary Convert the given argument to an instance of Date.
*
* @description
* Convert the given argument to an instance of Date.
*
* If the argument is an instance of Date, the function returns its clone.
*
* If the argument is a number, it is treated as a timestamp.
*
* If an argument is a string, the function tries to parse it.
* Function accepts complete ISO 8601 formats as well as partial implementations.
* ISO 8601: http://en.wikipedia.org/wiki/ISO_8601
*
* If all above fails, the function passes the given argument to Date constructor.
*
* @param {Date|String|Number} argument - the value to convert
* @param {Object} [options] - the object with options
* @param {0 | 1 | 2} [options.additionalDigits=2] - the additional number of digits in the extended year format
* @returns {Date} the parsed date in the local time zone
*
* @example
* // Convert string '2014-02-11T11:30:30' to date:
* var result = parse('2014-02-11T11:30:30')
* //=> Tue Feb 11 2014 11:30:30
*
* @example
* // Parse string '+02014101',
* // if the additional number of digits in the extended year format is 1:
* var result = parse('+02014101', {additionalDigits: 1})
* //=> Fri Apr 11 2014 00:00:00
