Minor cleanup
Added more test cases on cv::Mat usage
Added reshape function
Added utils/print.hpp for printing to std::ostream
Ported matlab function imquantize
Cleaning up standardize

Removed data scaling because actually numerical differences between
Matlab and OpenCV shoul be tolerated.
Added usage test for OpenCV color conversion
Added HSV conversion and quantization functions
Fix after test
Added HSV histogram computation
Added HSV histogram normalization option
Added rendering of HSV quantized image
Added function for printing 3D Matrices

Printing to cout is disabled for multidimensional matrices in OpenCV.
Added r2c and c2r for row-major and column-major indexing
Added note for using cvRound instead of boost::math::round
