ImSim: Image Similarity

[n00m]

I uploaded a new version of the subject with a
VERY MINOR correction in it. Namely, in line #55:

    print '%12s %7.2f' % (db[k][1], db[k][0] / 3600.0,)

instead of

    print '%12s %7.2f' % (db[k][1], db[k][0] * 0.001,)

I.e. I normalized it to base = 100.
Now the values of similarity can't be greater than 100
and can be treated as some "regular" percents (%%).

Also, due to this change, the *empirical* threshold of
"system alarmity" moved down from "number 70" to "20%".
