// History:
// -----------
// 31 Jul 2001 MGP Created, with dummy implementation
// 12.09.01 V.Ivanchenko Add param and interpolation of parameters
// 04.10.01 V.Ivanchenko Add BindingEnergy method
// 25.10.01 MGP Many bug fixes, mostly related to the
// management of pointers
// 29.11.01 V.Ivanchenko New parametrisation + Excitation
// 30.05.02 V.Ivanchenko Format and names of the data files were
// chenged to "ion-..."
// 17.02.04 V.Ivanchenko Increase buffer size
