[Insight-developers] New itkTransformBase class

[Julien Jomier]

Hello,

I'm writing a TransformFileReader/Writer based on metaIO.
For the moment everything is going smoothly. I just need to add a 
non-templated class between the itkObject and the itkTransform. I came 
up with an itkTransformBase class from which the current itkTransform 
derives.

Let me know if you see any problems in doing so.
If there is no issue, I'll check the new class in next week,

thanks,

Julien
