Plot span of fitted frequencies in vib_anayze.py.

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.
