class TEveJetCone: public TEveElementList, public TAttBBox


 Draws a jet cone with leading particle is specified in (eta,phi) and
 cone radius is given.

 If Apex is not set, default is (0.,0.,0.)
 In case of cylinder was set, cone is cut at the cylinder edges
 example :

  Float_t coneEta    = r.Uniform(-0.9, 0.9);
  Float_t conePhi    = r.Uniform(0.0, TwoPi() );
  Float_t coneRadius = 0.4;

  TEveJetCone* jetCone = new TEveJetCone("JetCone");
  jetCone->SetCylinder( 250., 250. );
  if ( (jetCone->AddCone( coneEta, conePhi, coneRadius   ) ) != -1)
    gEve->AddElement( jetCone );
