   * ### Options
   *
   * - **timezone**: The timezone that yielded occurrences should be *displayed* in.
   *   Note, this one affects the *displayed* timezone of yielded occurrences.
   *   For rules, occurrences are first found using the unmodified rule
   *   config (including whatever timezone the `start` datetime is defined
   *   in), and then converted to the timezone specified here before being
   *   yielded. By default, the timezone is *local* time (`null`). So if you don't
   *   want your rules to be displayed in local time, you must supply a
   *   timezone argument.
   * - **data**: arbitrary data you can associate with this Calendar. This
   *   is the only mutable property of `Calendar` objects.
   * - **maxDuration**: currently unused.
   * - **schedules**: either an occurrence generator, or an array of occurrence generators, which should
   *   be used to build up this Calendar's occurrences. The Calendar will display the union of occurrences
   *   its schedules produce.
