 * @brief Abstract event atom container class
 *
 * This class is an abstract container class for event atoms.
 *
 * In addition to the base class methods, it defines also an interface to the
 * region of interest (ROI) that is covered by the data space. The ROI can
 * be accessed by the roi() methods.
