// PlotMillePedeIOV is a class to plot the IOV dependence of pede parameters
// in case of run-dependend alignment, e.g. for large pixel structures.
// It makes internal use of PlotMillePede and also interfaces
// various selection settings of that class, see PlotMillePede.h.
// (Missing selection possibilities should be simple to add...)
//
// Management of the created histograms is done using the ('ancient')
// class GFHistManager, see description in PlotMillePede.h.
//
// By calling new PlotMillePedeIOV::Draw..(..) commands, usually previously
// drawn canvases are deleted. But if the option 'add' is given, canvases
// from previous Draw-commands are kept (in fact they are re-drawn).
//
// EXAMPLE I: full scale alignment with time dependent large pixel structures
// 
// PlotMillePedeIOV i("treeFile_merge.root");
// i.SetSubDetId(1);      // Select BPIX.
// i.DrawPedeParam("x");
// i.SetSubDetId(2);      // Select FPIX...
// i.AddAdditionalSel("z", 0,100); // ...but only positive z.
// i.DrawPedeParam("add x z");
// i.ClearAdditionalSel();           // Remove selection on z >= 0... 
// i.AddAdditionalSel("z", -100, 0); // ... and request negative z.
// i.DrawPedeParam("add x z");
//
//
// EXAMPLE II: time dependent alignment of large pixel structures
//             using inversion (i.e. errors available), no hierarchy involved
// 
// PlotMillePedeIOV i("treeFile_merge.root");
// i.SetHieraLevel(0); // no hierarchy => lowest level (default is 1, see ctr.)
// i.SetSubDetId(1);      // Select BPIX.
// i.DrawPedeParam("x");
// i.DrawPedeParam("x val"); // same but without error bars
// i.DrawPedeParam("x err add"); // now draw errors vs IOV
// i.SetSubDetId(2);      // Select FPIX...
// i.DrawPedeParam("x val add");
// i.DrawPedeParam("x err add");
