some work, trying to be smart with contour segments though curvature analyses.
more work on pupil detection.
more work, added pupil debug window
adding ellipse fit error estimation, option to do nearest neighbor  texture interpolation
incremental work, its broken now...
adding some combinatorial search routines.
remove old fns
added custom combination fn
cosmetics, comments.
split pupil detectors into multiple files
started implementation of new canny edge based combinatorial detector
more work on pupil detector.
adding pupil history.
first working version. need optimization to decrease cpu time.
more work.
small improvements. Returning pupil now.
small optimizations.
adding confidence measure, quick exit when the solution is at hand and we have confidence in our prior.
small optimization: don't evaluate contours if you already have a good solution.
fixed conditional import
changed sample video
ux improvement for debug window
