//             by Mikhail Kossov, Sept 1999.
//  class header for Chipolino (Double Hadron) in CHIPS Model
// ----------------------------------------------------------
// Short description: In the CHIPS model not only hadrons are considered,
// but the di-hadrons, which can not be convereged to the quark content
// of only one hadron (e.g. pi+pi+, K+p, Delta++p etc). This kind of
// hadronic states, which can be easily decayed in two hadrons, is called
// Chipolino-particle in the model.
