Connected Square Detection

[ks07]

The new thresholding approach is limited in the number of boxes we can detect, at least without a more accurate kinect or a bigger play area. We could alleviate this by allowing boxes with the same height, with sufficiently differing geometries that we can split a solid shape into two squares accurately. Perhaps a square box and very-non-square box (also know as rectangular) would make this easy. Drastically different sizes would also help.
