Ok I have now written some code that writes the registered image to disk
after a sequence of N iterations.

In the future I hope to  enable movement of control points in my
application. Therefore I would also like to plot the current position of the
control points on the current registered image.

I am working on the following idea. When I store the current registered
image, I write the position of the control points to a file.

Later I can (hopefully) in eg. gnuplot load the image and read in the
corresponding control points and plot them on top of the image.

If anyone know of a better/easier way (maybe ITK already has examples
showing this?) they are most welcome to give suggestions!
