/**
* @name isSameISOWeekYear
* @category ISO Week-Numbering Year Helpers
* @summary Are the given dates in the same ISO week-numbering year?
*
* @description
* Are the given dates in the same ISO week-numbering year?
*
* ISO week-numbering year: http://en.wikipedia.org/wiki/ISO_week_date
*
* ### v2.0.0 breaking changes:
*
* - [Changes that are common for the whole library](https://github.com/date-fns/date-fns/blob/master/docs/upgradeGuide.md#Common-Changes).
*
* - The function was renamed from `isSameISOYear` to `isSameISOWeekYear`.
* "ISO week year" is short for [ISO week-numbering year](https://en.wikipedia.org/wiki/ISO_week_date).
* This change makes the name consistent with
* locale-dependent week-numbering year helpers, e.g., `getWeekYear`.
*
* @param {Date|Number} dateLeft - the first date to check
* @param {Date|Number} dateRight - the second date to check
* @returns {Boolean} the dates are in the same ISO week-numbering year
* @throws {TypeError} 2 arguments required
*
* @example
* // Are 29 December 2003 and 2 January 2005 in the same ISO week-numbering year?
* var result = isSameISOWeekYear(new Date(2003, 11, 29), new Date(2005, 0, 2))
* //=> true
