[Insight-developers] itk::Path needs static dimension constant

[Zachary Pincus]

Hi folks,

I have noticed that itk::Path does not define a static dimensionality  
constant like all other classes which take a VDimension template  
parameter.

I propose to add these lines to the header:
   /** Path dimension. The dimension of a path is fixed at  
construction. */
   itkStaticConstMacro(PathDimension, unsigned int, VDimension);

I would ordinarily just commit the changes, but since I don't know  
the status of the 2.6 release (and the cvs might be locked down  
anyway), I won't. However, I propose that this change be incorporated  
sooner rather than later. Since there's no way this can break  
anything, and since the Path class is far less useful without it,  
this constant ought to make it in soon.
