Also incorporated a function to set the eye model manually using a filtered eyeball. This makes the computation and projection/unprojection of ellipses easier in main.
- removed overloaded functions for getcandidates and refinepoints: resulting function now only uses Opencv's Point instead of Point2f
- added getDarkestPixelBetter to replace getDarkestPixel: this handles cases where glints cause very dark pixels to appear (primarily in the Vive benchmark videos). This also makes pupil detection slightly more robust.
- added initial glint handling code to refinePoints (not currently active)
- misc documentation
