OK, great.

As far as I can tell, the Registration classes are nearly the same
apart from some cleanup.  The Metric class underwent refactoring.  The
best hint as to what is going on appears to be:

 * The improvment implemented here is about
 * the precomputation of the internal kernels proposed by Lange et al.:
 * \link http://www.zib.de/lamecker/publications/cars2007.pdf

Comparing the output of the tests, the registered tube resampled onto
an image, the "2" result does not resemble the input image (as far as
I can tell).

Is there a way to visualize the tube spatial object directly?  It is a
MetaIO ".tre" file containing a Scene, Group, and Tube ObjectType.  I
assume Slicer should recognize it as a "Model", but it seems to think
it is a "Volume".

Thanks,
Matt
