Eddystone Beaconing samples

There are two samples available for Eddystone beaconing. Both of which require the provided Eddystone Library. 

The first sample, eddystone_advertise, which forms and advertises the three types of beacons the library supports.

The second sample, eddystone_parse scans for beacons and prints out any Eddystone beacons it discovers.
