[Insight-developers] Removing SpatialOrientation stuff from itk::ImageBase

[Kent Williams]

My proposal for removing SpatialOrientation stuff from itk::ImageBase 
(scroll to the bottom):

http://www.itk.org/Wiki/Proposals:Orientation#Cosine_Direction_Vectors.2C_and_itk::SpatialOrientation_.28Kent_Williams.29

In summary, the conversion betwee SpatialOrientation and Direction 
Cosines is moved to a template 'helper' class.  I'm open to 
discussions/suggestions on whether this is the way to go -- the drawback 
to the scheme presented is that it requires partial template 
specialization to handle general N-dimensional orientation 
representations elegantly.
