 /***********************************************************************
 *
 * \brief Class that offers a convenient way to switch between different
 * interaction schemes
 *
 * This class offers the possibility to switch between the two different
 * interaction schemes that are available:
 * - MITK : The original interaction scheme
 *   - left mouse button   : setting the cross position in the MPR view
 *   - middle mouse button : panning
 *   - right mouse button  : zooming
 *
 *
 * - PACS : an alternative interaction scheme that behaves more like a
 *          PACS workstation
 *   - left mouse button   : behavior depends on current MouseMode
 *   - middle mouse button : fast scrolling
 *   - right mouse button  : level-window
 *   - ctrl + right button : zooming
 *   - shift+ right button : panning
 *
 *   There are 5 different MouseModes that are available in the PACS scheme.
 *   Each MouseMode defines the interaction that is performed on a left
 *   mouse button click:
 *   - Pointer : sets the cross position for the MPR
 *   - Scroll
 *   - Level-Window
 *   - Zoom
 *   - Pan
 *
 * When the interaction scheme or the MouseMode is changed, this class
 * manages the adding and removing of the relevant listeners offering
 * a convenient way to modify the interaction behavior.
