Closing some issues!
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.
NTP configuration file was missing
Measure screen should be able to measure fiducial locations on a fully-illuminated screen.
Introduced multiplicative factor to voltages for increased precision
Sensor edges as limb crossings now correctly applied only when sun is against edge of sensor
Merge remote-tracking branch 'origin/ntp' into mount
Mounting of external drives now done by service instead of fstab
Fixed missing reflection in Transform class
Changed Transform time input to timespec (for subsecond calculations)
Removed redundant ntp.conf
New PointingTest program to reanalyze saved images for pointing
Bug fixes to Transform time handling
Telemetered temperatures and voltages are now 8-frame averages
