Proposal for Revised Framework

Let us suppose we want to perform a registration with the new framework.

There are a few key ingredients we need:

1. itkComposeTransform class , derived from itkTransform

2. itkDeformationFieldTransform class , derived from itkTransform

3. itkTransformImageFilter --- takes itkTransform as input

Then , pseudocode for a registration is:

1. Set up a multi-resolution optimization over the TransformImageFilter

2. For each transform within itkComposeTransform

--- Optimize: the metric(s) associated with that transform for n iterations or convergence

3. go to next level

For the Optimize step:
