Class Description

 TMCFastHepParticle

 These are the particle contained in the TClonesArray from TMCFastHepEvt

 This class is an object oriented version of StdHep FORTRAN common block.
 The StdHep common block is filled by MCFast routines. A TClonesArray of
 TMCFastHepParticle is created by
 TMCFastHepEvt::Fill(common block information)

 More information about StdHep can be found at:

/*

http://www-pat.fnal.gov/stdhep.html 
*/

TMCFastHepParticle(struct heppart_t *part,Int_t index)

  This Calls Fill()

void Fill(struct heppart_t *part,Int_t index)

Fill the object information using a c struct map
of the Fortran common block used in mcfast

~TMCFastHepParticle()

 call Clear()

void Print(ostream *os)

 Prints TMCFastHepParticle object

 This function is also used
 to  overload  &operator<<

 For example;
 cout << heppart;

 where heppart is an instance of TMCFastHepParticle
