	This file contains the old history information of the EvtGen package
	from the LHCb collaboration, starting from the original version from
	D.Lange and A.Ryd. This history is now superseded by the History.txt file.

	=============================================================================

	! 2011-01-05 - John Back
	- EvtTensor4C.cpp: Correction to EvtTensor4C::cont() from Anders Ryd
	- EvtParticle.cpp: Removed assert from generateMassTree()

	!========================= EvtGen v12r0 2010-12-09 ==========================
	! 2010-12-09 - John Back
	Below is a summary of the merge between the latest BaBar & LHCb EvtGen code.
	- EvtCPUtil.cpp: Class interface changed to use static instance and not
	static functions. There are now two OtherB functions for coherent and
	incoherent B pairs (set to incoherent by default for LHCb).
	- EvtGen.cpp: Added extra integer argument in constructor to choose
	EvtCPUtil OtherB function type. Default is set to incoherent B pairs.
	Removed CLHEP includes.
	- All CP violation model classes: changes for new EvtCPUtil::OtherB()
	interface.
	- EvtLASSAmp.cpp: Added two sub-amplitude types LASS_ELASTIC and
	LASS_RESONANT. The constructor takes an additional string to specify
	what amplitude is used (default is set to LASS, the original version).
	- Added EvtBaryonPCR and EvtBaryonPCRFF models for baryonic semileptonic
	decays using more realistic dynamics.
	- EvtModelReg.cpp: Added EvtBaryonPCR model.
	- Added EvtSemiLeptonicBaryonAmp.cpp for the above baryon models.
	- EvtSemiLeptonicFF.hh: Added getdiracff() and getraritaff() methods for
	the new baryon models. Since other semileptonic models (ModelNameFF.cpp)
	use this class, they also need to implement these new methods (which
	actually do no extra calculations).
	- Changed EvtWilsonCoeficients to EvtWilsonCoefficients, used in
	EvtGenModels/EvtLb2Lll.hh.

	!========================= EvtGen v11r10 2010-10-12 ==========================
