 `SwiftMessagesSegue` generally requires configuration to achieve specific layouts and optional behaviors. There are a few good ways to do this:
 
-  1. __(Recommended)__ Subclass `SwiftMessagesSegue` and apply configurations in `init(identifier:source:destination:)`. Subclasses will automatically appear in the segue type dialog using an auto-generated name. For example, the name for "VeryNiceSegue" would be "very nice".
