   *
   * \brief Class that offers a convenient way to switch between different
   * interaction schemes and their different modes.
   *
   * 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
   *
   *   There are 3 different MITK modes that are available in the MITK scheme.
   *
   * - 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 PACS modes that are available in the PACS scheme.
   *   Each mode 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 is changed, this class sets the corresponding
   * interaction .xml-files for a given interaction event handler.
   *
