final 2D gabor implementation

made some mild changes for efficiency

made the function accept both gray level and color images by default, changed the ordering of the smoothing operations to make it more effective at finding the pupil, and less prone to losing the pupil to noise

future versions of matlab will be changing how the circular shift will work, so this makes it future proof

removed the hough transform pictures from being shown by default

further information on running the codes in the readme

added information on running the codes

added preprocessing, performance of which can be seen in the report, made the various counters more specific and attempted to find why the gabor encoding is getting such low performance

commenting

added optional bit shifting to hamming

removed old gabor function

new gabor filter

re-structured the plots

updated script to run the iris detection, unwrapping, and gabor encoding using libor, as well as plotting some figures of it all
