Finished testing JcvMatND

JcvMatND the multidimensional OpenJCV matrix class has been JUnit tested! From this point, I'm going to follow more of a critical path through the development and testing of OpenJCV. That is, I'm moving on to the final development and complete testing of the image packages (display, conversion to/from matrices, reading/writing, etc). After that, I'll jump right into the implementation of some basic image processing and computer vision algorithms.
