 The Ui Library is used to provide a basic set of Ui elements called, `Frames` and `Overlays`. A `Frame` is used to provide
 information the default behaviour is to display a `Frame` for a defined time and than move to the next. The library also provides an `Indicator` that will be updated accordingly. An `Overlay` on the other hand is a pieces of information (e.g. a clock) that is displayed always at the same position.
