           Maurik Holtrop 06-02-2005
	   I added the ST stat pointer back into the code, since EG3 will need
	   the ST information.
	   Hovanes 12-2006:  Changed UChar_t to Char_t for status words.
This class is a base class for storing data. The classes TEVNTClass and TGSIMClass derive from it. Any new datacontainer class should also derive from this class. This allows the classes, which contain the same data, to be mixed more easily.
Most methods for dealing with data directly belong in this class.
TVirtualData(TVirtualData *TmpEVNT)
void Print()
Float_t GetMass()
 Get the CALCULATED mass, from p and beta.
 I.E. mass= P * Sqrt( 1/(beta*beta) - 1)

 Will return -1. if beta<=0, or beta>1 .

 You can get the exact mass of a particle with:

 M=TClasTool::fgParticle_Mass[kPion_Plus_Id];
 or
 M=TClasTool::GetPartMassID(evnt->GetId());
 which uses TClasTool::GetTypeFromPid(pid) to look up
 the particle.

 Alternatively, in root version>4 you can also do
 the following:
 You can get the PDG value for the particle with Id 
 the following way:
 First Load the libEG.so --> .L $ROOTSYS/lib/libEG.so
 Then call:

 M=TDatabasePDG::Instance()->GetParticle(evnt->GetId())->Mass();

 This will give the exact PDG mass (i.e. 1.3957e-01 for a pi-)
