[Insight-developers] NumericTraits for DiffusionTensor3D

[Luke Bloy]

Hi Brad,

Unfortunately the macros used in itkNumericTraitsTensorPixel.h can't be 
used for the DiffusionTensor3DPixels, since the DiffusionTensor3Dpixels 
are not templated over the 'vectordimension'

The macro I defined is based off those that are defined in 
http://public.kitware.com/cgi-bin/viewcvs.cgi/Code/Common/itkNumericTraitsFixedArrayPixel.h?revision=1.8&root=Insight&view=markup
and used in itkNumericTraitsTensorPixel.h
