In order to convert a stream of characters into objects representing keystrokes, we need to apply logic on this
stream to detect special characters. In lanterna, this is done by using a set of character patterns which are matched
against the stream until we've found the best match. This interface represents a set of such patterns, a 'profile'
with is used when decoding the input. There is a default profile, DefaultKeyDecodingProfile, which will probably
do what you need but you can also extend and define your own patterns.
