Added a test that slightly changes the ray direction in the XY-plane.
Added two tests, parallel to XY and XZ planes. (Note: These may change when the code is updated, since its along an angular boundary).
Note: Trying this test in the XZ plane, i.e. ray direction = [1, 1, 1.5] claims that only 5 voxel traversals occur. Its difficult to determine whether this is true or not, even with spherePlot.py. Does this mean the ray is exiting from the top early?
