Updates to MAC / UAV protocols

[dlebauer]

A few bits of information that may be useful (not urgent) for the UAV protocols:

• information about pilot, company
• link to datasets on Clowder
• metadata
  • add / link to sensor meta-data (bands, etc)
  • add / link to reference white, grey, black tarp metadata
• figures:
• images of eBee and hexacopter
• sample image with polygon overlays

@dlebauer
I see information about the pilot and company in terraref/computing-pipeline#185 and I see the datasets in Clowder.

Is there information about the sensors, ebee and hexacopter in Drive someplace?
