 /** \brief  A matrix of image cells with reordering
 *
 * This calls allows you to create a matrix of image cells that can be
 * reordered (similar to object in an outline view).  To use this class
 * add it to your project.  In InterfaceBuilder create a matrix of
 * ImageViews.  In the properties pane go to custom class and set the class
 * to DragMatrix.  When a image is dragged this class sends a notification
 * "DragMatrixImageMoved".  The object is itself.  The user info contains
 * the following keys
 * 	- "images" = Selected DicomImages
