-This view allows a user to enter a pin or code (for security/mobile verification etc) of any length. It allows deletion, continuation and allows you to get the entire entered code as a single String or Int without having to join Strings from multiple text fields. It's fast, looks nice (I think) and is customisable! Requires iOS 9+.

 There is now also an error mode which can be toggled with `entryView.toggleError()`. It is automatically removed if the user taps on the field or starts typing again.
