Initial Push of Arduino Sample Apps
Right now, tokens are messed up. I cannot get Observe operation to

Patch Set 2: Removed "local.properties." This file should NEVER be
committed.
Patch Set 4: Made changes to READMEs as proposed by Bill Dieter.
Patch Set 5-7: Rebases
Path Set 8: Updated stack files to build for Arduino as well.
Arduino compiler is a little bit more per-snickety than the linux compiler.
