* @name roundToNearestHours
* @category Hour Helpers
* @summary Rounds the given date to the nearest hour
*
* @description
* Rounds the given date to the nearest hour (or number of hours).
* Rounds up when the given date is exactly between the nearest round hours.
*
* @typeParam DateType - The `Date` type, the function operates on. Gets inferred from passed arguments. Allows to use extensions like [`UTCDate`](https://github.com/date-fns/utc).
*
* @param date - The date to round
* @param options - An object with options.
*
* @returns The new date rounded to the closest hour
*
* @example
* // Round 10 July 2014 12:34:56 to nearest hour:
* const result = roundToNearestHours(new Date(2014, 6, 10, 12, 34, 56))
* //=> Thu Jul 10 2014 13:00:00
*
* @example
* // Round 10 July 2014 12:34:56 to nearest half hour:
* const result = roundToNearestHours(new Date(2014, 6, 10, 12, 34, 56), { nearestTo: 6 })
* //=> Thu Jul 10 2014 12:00:00
* @example
* // Round 10 July 2014 12:34:56 to nearest half hour:
* const result = roundToNearestHours(new Date(2014, 6, 10, 12, 34, 56), { nearestTo: 8 })
* //=> Thu Jul 10 2014 16:00:00
* @example
* // Floor (rounds down) 10 July 2014 12:34:56 to nearest hour:
* const result = roundToNearestHours(new Date(2014, 6, 10, 1, 23, 45), { roundingMethod: 'ceil' })
* //=> Thu Jul 10 2014 02:00:00
*
* @example
* // Ceil (rounds up) 10 July 2014 12:34:56 to nearest quarter hour:
* const result = roundToNearestHours(new Date(2014, 6, 10, 12, 34, 56), { roundingMethod: 'floor', nearestTo: 8 })
* //=> Thu Jul 10 2014 08:00:00
