TinyOS, TOSSIM and the Yeti2 plugin for Eclipse

I've wrestled with this for quite some time. Everything worked except the tossim code kept showing as an error in Eclipse.

I had added the tossim folder as an include location, but it didn't seem to matter. I finally tried clicking on some of the settings and found that by left clicking you toggle through the options. So after I made the settings look as in the image, my TOSSIM errors finally went away.

NCC: Consider, default was ignore
Include: Source, default was never
Search: Recursive, default was flat
