[Insight-developers] Registration classes

[Luis Ibanez]

The registration classes have been modified
to factorize some common aspects.

Now they derive from itkRegistrationMethod,
which derives from itkProcesObject.

itkRegistrationMethod receives a Traits class,
pretty much as itkMesh does.


Additionally, the name of the optimization method
was added at the end of the registration method name.


The PointSet to Image registration methods still
need some debuggin to verify that they are doing
the right thing at run time, but by now they are
compiling fine.

Some of these methods will be available in the
example at /Examples/ImageRegistration.

There's still some need for communication between
the registration methods and the GUI....
