/**
 * @name areIntervalsOverlapping
 * @category Interval Helpers
 * @summary Is the given time interval overlapping with another time interval?
 *
 * @description
 * Is the given time interval overlapping with another time interval? Adjacent intervals do not count as overlapping unless `inclusive` is set to `true`.
 *
 * @param intervalLeft - The first interval to compare.
 * @param intervalRight - The second interval to compare.
 * @param options - The object with options
 *
 * @returns Whether the time intervals are overlapping
 *
 * @example
 * // For overlapping time intervals:
 * areIntervalsOverlapping(
 *   { start: new Date(2014, 0, 10), end: new Date(2014, 0, 20) },
 *   { start: new Date(2014, 0, 17), end: new Date(2014, 0, 21) }
 * )
 * //=> true
 *
 * @example
 * // For non-overlapping time intervals:
 * areIntervalsOverlapping(
 *   { start: new Date(2014, 0, 10), end: new Date(2014, 0, 20) },
 *   { start: new Date(2014, 0, 21), end: new Date(2014, 0, 22) }
 * )
 * //=> false
 *
 * @example
 * // For adjacent time intervals:
 * areIntervalsOverlapping(
 *   { start: new Date(2014, 0, 10), end: new Date(2014, 0, 20) },
 *   { start: new Date(2014, 0, 20), end: new Date(2014, 0, 30) }
 * )
 * //=> false
 *
 * @example
 * // Using the inclusive option:
 * areIntervalsOverlapping(
 *   { start: new Date(2014, 0, 10), end: new Date(2014, 0, 20) },
 *   { start: new Date(2014, 0, 20), end: new Date(2014, 0, 24) },
 *   { inclusive: true }
 * )
 * //=> true
