Hildon::Banner is a pseudo class in most cases because it provides mainly static methods. It is used to show a little popup window at the top-right
corner of the screen. These can contain text, progressbars and animation icons. You only need an object of Hildon::Banner if you want to show
a progressbar. If you are familiar to the GNOME framework, the concept is similar to libnotify.
This examples show all possibilites you have with Hildon::Banner: A simple text, a progressbar and an animation.
