AssertionError : points2D.shape[0] == points3D.shape[0] #40

For some reason I get this error. I do point matching according to video tutorial, but after I choose 4 points (5 clicks) on image and 4 points (5 clicks) on cloud and close both windows I get this error. I printed the actual shapes and it was 24 points in 2D list and 82 points in 3D list.

see #27 and #6, delete .npy temp files
