30 curves of octomeric-I27 using a modified MultiMode [1].

Contributed by W. Trevor King.

Note that the bulk of the cantilever calibration data has been left
out of calibrate_cantilever/20100504/ to save space.  We retain only
the summary output file 20100504134510_calib_analysis_text.

In a production environment, other days' experiments and calibration
data goes into other YYYYMMDD-stamped subdirectories of unfold/ and
calibrate_cantilever/, so we retain that directory structure here.


[1]: MultiModes were orignally by Digitial Instruments, which was
bought by Veeco in 1998.  Veeco sold its metrology wing (including the
MultiMode line) to Bruker in 2010.
