Added an open menu delegate that will get fired when the user select the button to open the menu.
Corrected the close menu delegate so that it is not fired for every button of the menu. It will now only fire once.
Changed both open menu and close menu delegates to fire asynchronously
Updated README
Updated for Swift 3.2 (.pi updates)
