/**
 * @name parseISO
 * @category Common Helpers
 * @summary Parse ISO string
 *
 * @description
 * Parse the given string in ISO 8601 format and return an instance of Date.
 *
 * Function accepts complete ISO 8601 formats as well as partial implementations.
 * ISO 8601: http://en.wikipedia.org/wiki/ISO_8601
 *
 * If the argument isn't a string, the function cannot parse the string or
 * the values are invalid, it returns Invalid Date.
 *
 * @param {String} argument - the value to convert
 * @param {Object} [options] - an 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
 * @throws {TypeError} 1 argument required
 * @throws {RangeError} `options.additionalDigits` must be 0, 1 or 2
 *
 * @example
 * // Convert string '2014-02-11T11:30:30' to date:
 * const result = parseISO('2014-02-11T11:30:30')
 * //=> Tue Feb 11 2014 11:30:30
 *
 * @example
 * // Convert string '+02014101' to date,
 * // if the additional number of digits in the extended year format is 1:
 * const result = parseISO('+02014101', { additionalDigits: 1 })
 * //=> Fri Apr 11 2014 00:00:00
