// PlotMillePede is a class to interprete the content of the ROOT
// TTrees that are stored as output of the millepede alignment algorithm.
// The histograms are created by the methods inherited from the
// MillePedeTrees class. Drawn quantities and selections are handled
// as strings as they can be understood by TTree::Draw(..) commands.
//
// The main methods all start with 'Draw', so you can use tab completion
// on what is available:
//     PlotMillePede p("treeFile.root"); // file form pede step
//     p.Draw<tab>
//
// Management of the created histograms is done using the ('ancient')
// class GFHistManager. A pointer to that class can be accessed by
//     GFHistManager *man = p.GetHistManager();
// and then be used manipulate the drawings, e.g. by  
//     man->SetLogY();
// or
//     man->SetNumHistsXY(3,1);
//     man->Draw();
//
// By calling new p.Draw..(..) commands, usually previously drawn canvases are
// deleted. But most methods provide either a boolean flag 'addPlots' or
// understand the option 'add'. If the flag is true or the optione string
// contains 'add', canvases from previous Draw-commands are kept (in fact they
// are re-drawn).
//
// A title can be set by 'void SetTitle(const char *title)':
// The title will appear as part of all histogram titles.
//
// Several cuts can be set and are active until reset for all drawing routines
// called after setting them. Active selections are mentioned in histogram titles.
// The possibilites to set cuts are:
//
// 1) Select subdetector(s):
// void SetSubDetId(Int_t subDetId);
//  *  1-6 are TPB, TPE, TIB, TID, TOB, TEC, 
//  *  -1 means: reset, i.e. take all
//  * using (repeated) calls of
//    void AddSubDetId(Int_t subDetId);
//    leads to an OR selection of subdetectors
//
// 2) Special alignable types:
// Int_t SetAlignableTypeId(Int_t alignableTypeId);
//  * DetUnit=1,
//  * Det=2,
//  * TIBString=15,
//  * etc. from CommonAlignment/interface/StructureType.h 
//  * -1 resets
// The methods returns the previous setting.
//
// 3) Select hierarchy level:
// In case of hierarchical alignment, one can look at the parameters etc. of each 
// (active!) hierarchy level separately:
// Int_t SetHieraLevel(Int_t hieraLevel);
//  * 0 (default!): lowest level only
//  * 1,2,...: first, second,... larger structures only
//  * -1: resets, shows all levels
// The methods returns the previous setting.
//
// 4) General selection:
// void AddAdditionalSel(const char *selection);
//  * whatever selection string that is valid on the TTree's...
//  * ... therefore for experts 
//  * current setting cleared by 'ClearAdditionalSel()'
//
// 4a) Strip stereo, rphi, 1Dlayer/double sided selection:
//  * Known keywords for AddAdditionalSel(..)
//     * StripStereo:     only Id's of stereo modules in 2D layers/rings 
//     * StripRphi:       only Id's of rphi modules in 2D layers/rings 
//     * StripDoubleOr1D: only Id's from 1D layers or composed Dets in 2D layers/rings
//
// 4b) Geometrical and N(hit) selection:
// void AddAdditionalSel(const TString &xyzrPhiNhit, Float_t min, Float_t max);
//  This method makes internal use of the above "AddAdditionalSel(const char *)".
//  Selects quantity 'xyzrPhiNhit' between 'min' and 'max' where
//  'xyzrPhiNhit' can be any of x, y, z, r, phi, Nhit.
//  Also cleared by 'ClearAdditionalSel()'.
