Good day! We have nested!! Woohoo!!

Continued work on the API.  At this point a full mate with a single sensor signal
works. In theory multiple signals work too but that's not yet tested.

Two new tables were added to the database and I'm now working on the 'compendium' code.

My stub generator has been fixed to properly produce Peacocks.

Up next: finish testing multi-signal Peacocks and get compendium code written
including the ability to delete known sensors.  Once that's done move on to the
Squawks.
