In trying to determine whether or not there was a water leak with the laser, the humidity sensor in the high
power oscillator was looked at.  In doing so, a interesting coincidence was noticed - the reason for which
is not obvious to me (anyway).

    WaterTrip1.png shows the humidity sensor output from last night when Jeff reported that the laser tripped.
WaterTrip2.png shows the same signal from when the laser tripped a few moments ago.  Both plots show a small
oscillation-like variation in the humidity.  The same behaviour shows up in the temperature sensors mounted
to the laser base plate.
