   * My Calendar III
   *
   * Implement a MyCalendarThree class to store your events. A new event can always be added.
   *
   * Your class will have one method, book(int start, int end). Formally, this represents a booking
   * on the half open interval [start, end), the range of real numbers x such that start <= x < end.
   *
   * A K-booking happens when K events have some non-empty intersection (ie., there is some time that
   * is common to all K events.)
   *
   * For each call to the method MyCalendar.book, return an integer K representing the largest integer
   * such that there exists a K-booking in the calendar.
   *
   * Your class will be called like this: MyCalendarThree cal = new MyCalendarThree();
   * MyCalendarThree.book(start, end)
   *
   * Example 1:
   *
   * MyCalendarThree();
   * MyCalendarThree.book(10, 20); // returns 1
   * MyCalendarThree.book(50, 60); // returns 1
   * MyCalendarThree.book(10, 40); // returns 2
   * MyCalendarThree.book(5, 15);  // returns 3
   * MyCalendarThree.book(5, 10);  // returns 3
   * MyCalendarThree.book(25, 55); // returns 3
   *
   * Explanation:
   *
   * The first two events can be booked and are disjoint, so the maximum K-booking is a 1-booking.
   * The third event [10, 40) intersects the first event, and the maximum K-booking is a 2-booking.
   * The remaining events cause the maximum K-booking to be only a 3-booking.
   * Note that the last event locally causes a 2-booking, but the answer is still 3 because
   * eg. [10, 20), [10, 40), and [5, 15) are still triple booked.
