 * Description:  Abstract base interface class for shower max objects         *

 * Revision History:                                                          *
 *    07-Oct-1999   Bob Wagner   Initial creation                             *
 *    15-Oct-1999   Bob Wagner   Change interface to provide a localCoord     *
 *                               accessor that returns a string and a double  *
 *                               string can be used to identify what the coord*
 *                               is and double is its value.  Remove the 3-d  *
 *                               space coord accessor                         *
 *    19-Oct.1999   Bob Wagner   Add accessors for detector, side, module,    *
 *                               view and local coordinate.  Local coordinate *
 *                               will now simply return a double              *
 *                               Also add print function                      *
 *    26-Oct-1999   Bob Wagner   Add a clone method to the class to allow for *
 *                               copying polymorphically                      *
 *    12-Nov-1999   Marc Paterno Made into a StreamableObject                 *
 *                               Added class_name() function                  *
 *    10-May-2000   Bob Wagner   Change return type of region() to Detector   *
 *                               which is enumeration in CalConstants.hh      *
 *                               Remove EDM2 directives.                      *
 *    01-Jun-2000   Dave Waters  Add version information.                     *
 *                                                                            *
