Adds a new message type that handles text that doubles the font size and removes the message background to model how iMessage displays emoji-only messages.
It seems as though when using a UINavigationController there is an issue with the rendering of an inputAccessoryView. This workaround creates a copy during the animation and then deletes it.
Added an `Avatar` property to the `AvatarView`
Replaced the `imageView` in the `MessagesCollectionViewCell` with the `AvatarView`
Moved the `Avatar.playground` to the example project so users can play around and learn it capabilities.
Updated the example project and abstracted the `sampleData` to its own file.
Updated the organization for the project to `MessageKit` instead of `Hex bits`
