Bug in FindFiducialIDs that was using hard-coded fiducial spacings
Clipping outlier values in FindFiducials to reduce number of erroneous fiducials.
Chords now search only on subimage when available. Should increase speed slightly.
Added a case to ignore chords that aren't significantly brighter than the threshold for a limb.
Measure screen should be able to measure fiducial locations on a fully-illuminated screen.
Sensor edges as limb crossings now correctly applied only when sun is against edge of sensor
Fixes to Alex's code for the Sun at sensor edges
Merge branch 'ac' into telemetry
