added code to transpose HOG from matlab layout to our usual 'depth = adjacent dim' layout. Currently just for file I/O conventions, but later on this might be 'real code'
writing result HOG to csv. results don't make a whole lot of sense ... in [0 1 2 ... 31] of each HOG descriptor, only element 1 is ever nonzero. strange.
visually, results look fairly reasonable from calling Piotr's FHOG from C++ and writing result to CSV. Next step: do some comparisons (and use downsampling?)
