/** 
 * Simple selection of a surfel (with shift + left click) with the
 * QGLViewer proposed by DGtal (Viewer3D). You may associates \a names
 * (i.e. integers) to surfels or to group of surfels. You may associate
 * reactions or callback functions to \a named graphical objects (surfels
 * in DGtal 0.9).
 *
 * The red surfel is given the name 10001, the green 10002 and the blue
 * 10003. A specific reaction is associated with surfel 10001, while a
 * common reaction is associated with surfels 10002 and 10003. The
 * reactions simply display the clicked surfel.
