This release introduces adds a new clear() method that adds a method for deleting Default objects.

Thanks @nitrag for putting this together!

Changes

• Writing an object to UserDefaults with Default is now accomplished with: write() or write(withKey:)
• Reading an object from UserDefaults is now accomplished with read() or read(forKey:)
• defaultValue has been added to the protocol, the default implementation returns nil can be customized to return a default value when nothing exists in defaults.
