[IGSTK-Developers] Accessing ITK image

[Patrick Cheng]

Hi everyone,

For the new demo application, the registration class need to get access 
to the ITK image, so that it can segment out the fiducial points. Other 
ImageToImage registration also requires access to the ITK image too.

This posts a problem to the igstkImageSpatialObject class, if the user 
need to use their own registration class, they need to modify the 
igstkImageSpatialObject class and declare their registration class to be 
a friend class.

Is there a better solution to this problem?
