	// Description:Implementation of the ISGW2 model
	// Class to handle semileptonic decays using the ISGW2
	// model, as described in PRD 52 5 (1995) by
	// Isgur and Scora. Electron, muon, and tau models
	// are available. Form factors, q2 and lepton energy
	// spectra checked against code from Scora.
	//
	// Modification history:
