Title: getDistanceAt new feature

Adding this feature because I was working with the pixels of the
grayImage with a loop and then needed a more accurate description of
distance for very few pixels, so I have to make something horrible like:

printf("%f \n",kinect.getDistanceAt((int)i%640, (int)i/640));

Now we could use:

printf("%f \n",kinect.getDistanceAt(i) );

To get this number, the other way could be using a pointer or something
but this to me is a more elegant solution, hope will be useful.
