Testing the stability of the low bits of the DAC.

We have a 10-bit DAC that we are commanding with 10 bits, and want to
find out the precision of each command, ie. to what precision we can
predict the actual output of the DAC for each command.

Test setup: 10-bit DAC, scaled to about ±5V, measured as a voltage by
the Keithley 2002.

We ran dactest.c for about 16 hours to write random DAC values and
accurately measure their output.

process.m calculates, for each of 1024 commanded value, the average,
min, max, and standard deviation of the measured voltages.
