/**
 * The class TimeStep is an iterator for dates. You provide a start date and an
 * end date. The class itself determines the best scale (step size) based on the
 * provided start Date, end Date, and minimumStep.
 *
 * If minimumStep is provided, the step size is chosen as close as possible
 * to the minimumStep but larger than minimumStep. If minimumStep is not
 * provided, the scale is set to 1 DAY.
 * The minimumStep should correspond with the onscreen size of about 6 characters
 *
 * Alternatively, you can set a scale by hand.
 * After creation, you can initialize the class by executing first(). Then you
 * can iterate from the start date to the end date via next(). You can check if
 * the end date is reached with the function hasNext(). After each step, you can
 * retrieve the current date via getCurrent().
 * The TimeStep has scales ranging from milliseconds, seconds, minutes, hours,
 * days, to years.

   * - Events are extended with a function `event.stopPropagation()` to stop

   * - An option `preventDefault` to stop all default browser behavior.
   *
   * Usage:
   *   var hammer = propagatingHammer(new Hammer(element));
   *   var hammer = propagatingHammer(new Hammer(element), {preventDefault: true});
   *
   * @param {Hammer.Manager} hammer   An hammer instance.
   * @param {Object} [options]        Available options:
   *                                  - `preventDefault: true | false | 'mouse' | 'touch' | 'pen'`.
   *                                    Enforce preventing the default browser behavior.
   *                                    Cannot be set to `false`.
