Badger is a generalized single purpose library for adding badges to drawables in general and menu items in particular.

sett (also set) - The earth or burrow of a badger.

Running with the Badger theme, it is all about the method sett. Home to the badger, it is comprised of many tunnels and several entrances. It is the ideal entry point to provide you with badges where mere drawables lived before.

The Badger.sett() methods add a BadgeDrawable to the original drawable. This results in a LayerDrawable with the BadgeDrawable added to the layer with id badger_drawable. If the original drawable is a LayerDrawable having a badge already set, this one gets reused instead.
