glitch with analog input on cRIO

[eugenebrooks]

We have swapped both the NI module and the
FIRST interface to it. Also, we have hooked
a battery direct to the NI module to provide
the voltage to read, to make sure
that it is not the interface. We have also
varied the sample rate. We know it is glitching
both on a recorded high and low water mark,
seen with printf, and a servo readout.
The system is being run on a good robot battery.

There isn't any complicated code around, so
I suppose it is time for me to start looking at
WPIlib.

The glitch value does vary, but appears to be
identical on a given powerup.
