/**
* @name roundToNearestMinutes
* @category Minute Helpers
* @summary Rounds the given date to the nearest minute
*
* @description
* Rounds the given date to the nearest minute (or number of minutes).
* Rounds up when the given date is exactly between the nearest round minutes.
*
* @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 minute
*
* @example
* // Round 10 July 2014 12:12:34 to nearest minute:
* const result = roundToNearestMinutes(new Date(2014, 6, 10, 12, 12, 34))
* //=> Thu Jul 10 2014 12:13:00
*
* @example
* // Round 10 July 2014 12:12:34 to nearest quarter hour:
* const result = roundToNearestMinutes(new Date(2014, 6, 10, 12, 12, 34), { nearestTo: 15 })
* //=> Thu Jul 10 2014 12:15:00
*
* @example
* // Floor (rounds down) 10 July 2014 12:12:34 to nearest minute:
* const result = roundToNearestMinutes(new Date(2014, 6, 10, 12, 12, 34), { roundingMethod: 'floor' })
* //=> Thu Jul 10 2014 12:12:00
*
* @example
* // Ceil (rounds up) 10 July 2014 12:12:34 to nearest half hour:
* const result = roundToNearestMinutes(new Date(2014, 6, 10, 12, 12, 34), { roundingMethod: 'ceil', nearestTo: 30 })
* //=> Thu Jul 10 2014 12:30:00
