 All methods are optional, with two notable exceptions:
 
 1) If you are using your own custom OSKActivity subclasses,
 you must provide the required view controllers if the built-in view controller are not used.
 
 2) If you have marked an activity as requiring in-app purchase, you must provide a purchasing view controller.
 Overshare does not have any built-in purchasing view controllers.
