// MHMuonPar
//
// This class is a histogram class for displaying muonparameters.
// The folowing histgrams will be plotted:
// - Radius (TH1F)
// - ArcWidth (TH1F)
// - ArcWidth/Radius vs Radius (TProfile) (it is the energy dependent
//   relative broadening of the muon ring)
// - Size Vs Radius
//
// Inputcontainer:
//   - MGeomCam
//   - MMuonSearchPar
//   - MMuonCalibPar
