added additional input params to histogram (reference img, tolerance, window size). Hist now chops off 20% of the left and right margins of a image instead of a constant 10
no longer rotating the image windows, instead rotating the histogram
added more options for reference image, tolerance and window size. Added drawCentroids function for debugging
removed dead code, added print statements for debugging, blur parameter now passed into Hist objects to toggle amount of blurring
removing window patches whose histograms are empty, keeping track of eigenvalues/vectors
experimenting with eigenval/vec distances
