/**
* @name set
* @category Common Helpers
* @summary Set date values to a given date.
*
* @description
* Set date values to a given date.
*
* Sets time values to date from object `values`.
* A value is not set if it is undefined or null or doesn't exist in `values`.
*
* Note about bundle size: `set` does not internally use `setX` functions from date-fns but instead opts
* to use native `Date#setX` methods. If you use this function, you may not want to include the
* other `setX` functions that date-fns provides if you are concerned about the bundle size.
*
* @param {Date|Number} date - the date to be changed
* @param {Object} values - an object with options
* @param {Number} [values.year] - the number of years to be set
* @param {Number} [values.month] - the number of months to be set
* @param {Number} [values.date] - the number of days to be set
* @param {Number} [values.hours] - the number of hours to be set
* @param {Number} [values.minutes] - the number of minutes to be set
* @param {Number} [values.seconds] - the number of seconds to be set
* @param {Number} [values.milliseconds] - the number of milliseconds to be set
* @returns {Date} the new date with options set
* @throws {TypeError} 2 arguments required
* @throws {RangeError} `values` must be an object
*
* @example
* // Transform 1 September 2014 into 20 October 2015 in a single line:
* var result = set(new Date(2014, 8, 20), { year: 2015, month: 9, date: 20 })
* //=> Tue Oct 20 2015 00:00:00
*
* @example
* // Set 12 PM to 1 September 2014 01:23:45 to 1 September 2014 12:00:00:
* var result = set(new Date(2014, 8, 1, 1, 23, 45), { hours: 12 })
* //=> Mon Sep 01 2014 12:23:45
