[ANN] Cache Annotations Extension - seeking feedback

[Anton Markov]

I am working on an extension that caches the results of the annotate command
and uses the cache to speed up annotations for this revision and all future
revisions of the file. 

I am looking for technical feedback on the code.

You can get the latest version from:

hg clone https://ucosp.kilnhg.com/Repo/UCOSP/Group/Cache-Annotations
Username: guest
Password: anonymous

Please see README.txt for usage information and design.txt for technical
details.


This work is part of an Undergraduate Capstone Open-source Project (UCOSP).
