Changed guessed Q from 5 to 1, which gives about the right breadth.
I'm dubious about the fit quality though. Looking at the fit.log
output after looking at the 20080919_cantA_tweak.vib data again reveals
After 4 iterations the fit converged.
final sum of squares of residuals : 9.6001e+08
rel. change during last iteration : -2.46003e-07
for the first curve, and similar residuals (and exactly 4 iterations)
for the other curves. Hmm. I should probably explicitly show the range
of frequency space I'm fitting in.

Added guessed Lorentzian plot option to vib_analyze.
This explains why my Lorentzians are occasionally too sharp...
For example, consider the 2nd and 4th fit in
cd ~/rsrch/data/z_piezo_calib/
cc_vib_analyze.py -ct 20080919_cantA_tweak.vib -pG
(I know, I know, should be rsrch/data/calibcant...)

Resistribute vib_analyze pylab.hold()s to avoid auto-generated axis.
With the previous setup, the first call to hold() created a subplot(111)
axis that the rest of the subplots wrote over. Ugly. Better now.

Crop vib_analyze pylab Lorentzian fitline when it goes off-axis.

Added fit-curve to vib_analyze's pylab output.
Gave up on the gnuplot output for now.

Fixed non-interactive pylab plotting setup in common.py
Also fixed spacing in analyze.py from last change and removed some
.pyc files from versioning.

Added ez_setup.py installation wrapper and cleaned up License info.

Began versioning.
