[EM] IRV proponents figure out how to make IRV precinct-summable

[Raph Frank]

I uploaded the example ballot .pdf file that the code uses to
http://groups.yahoo.com/group/RangeVoting/files/Ballot%20image/temp_ballot.pdf

Also, some intermediate files from processing the image0001.pnp file.

This is after determining the alignment points:

These are the images of each extracted box (after rescaling etc):

These are the same boxes after processing

It gets 7 of the 8 correct.  The only error is the blank box (5).

The main thing, atm, that causes errors is the boxes themselves, as
the processing interprets them as part of the handwriting.  I think
that shouldn't be to hard to fix, but would require that the extracted
boxes are processed to find out exactly where their boundary lines
are.  Currently, it is open loop, it is assumed that the alignment
points are determined exactly.

With that, it could end up with 85%+ (at least with my handwriting :) ).
