*
* If minimumStep is provided, the step size is chosen as close as possible

* The minimumStep should correspond with the onscreen size of about 6 characters

* 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().
