3.0.0

Updated for Swift 3

2.0.0

Changed how the suppressionInterval works to allow easy transition from recommend to force update policies. The new behaviour is to always make the call to check the version, but only call the completion handler if it's a forced update, or its a recommended update and the suppression window has lapsed

1.0.0

• Added the ability to set a suppression interval that will prevent calls until the window lapses.
• Also refactored things a little bit
