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
Ported medfilt2 function
Added median filter to HSV histogram computation
Added test fixtures

Using CMake to preprocess the "images.hpp" header file and insert fullpaths to
test images. Then the "fixtures.hpp" contains ready-to-use structs to be used
as test fixtures.
Fix ported functions

Some functions need a transpose input to be compatibile with Matlab
Added getNumBins to HsvExtractor
Added toBgr function
Fix image quantization
Partially fixed HSV histogram rendering

Histogram rendering is still not correct because the ind2sub
ported function works column-major instead row-major.
To be fixed ...
