Basic .gitignore
Initial experiments with figure location
easier debugging
Allow easy adjustment of pre-processing
Try Hough line detection
fix
code cleanup
Process all images ASAP
Highlight bounding boxes
more tweaking
Skip edge contours and clean up verbose logging
Save extracted images
Start building out command-line UI
Allow not saving extracted images
Reduce console noise
Slightly more sophisticated filtering

This still needs more thought to do something smarter but it reduces
noise to a more manageable level
lower log noise
Report bogus image files
Disable blurring as it's not clearly a win
Add dilation controls, make both dilate/erode optional

These changes make it easier to see the effect of the various
filters. With the addition of better contour filtering, the filters
are also significantly less necessary than before

Beefed up logging to make easier to test with huge runs
