This is a simple watchface example that demonstrates how to build a watchface that is compatible with all Pebble
platforms (aplite, basalt, chalk, diorite, emery). It makes use of graphics APIs graphics_fill_radial and
grect_inset, as well as demonstrates how to use new defines like PBL_RECT and PBL_ROUND. The app has also
been updated to use the UnobstructedArea APIs.
