Detailed Description

This class is designed to manage the image-based deformation part of the reconstruction.

As each manager class, it is created in the main program, all parameters are then set, checked, and the manager is initialized.
The manager is then used by the algorithm itself, where the function PerformDeformation() is called each time the data belongs to a new "gate".
The deformation functions are not multithreaded, therefore the threads are synchronized (inside the main loop of the main algorithm) before performing any image transformation.
