[PATCH RFC] Adding pit_plot.py

["Alan D. Brunelle" <Alan.Brunelle@hp.com>]

I'd appreciate it if has any comments on something I've been playing
with _before_ is push it out in the tree. Basically, it's another way to
visualize Q, D & C traces utilizing the xmgrace program. The work-flow
is something like:

% blktrace...
% blkparse -d bp.bin ...
% btt -i bp.bin -P pit ...
% pit_plot.py XXXXpit.dat
% xmgrace XXXXpit.agr

A quickly thrown together document can be found at:

The (crudely crafted) Python script is at:

http://free.linux.hp.com/~adb/2008-11-11/pit_plot.py

And the proposed patch would be at:
