0013 // Class to overlay hists with same names from (several) different files.
0014 // Constructor argument 'fileLegendList' is a comma separated list of files
0015 // and the legend entry corresponding to it, e.g.
0016 // "file1.root=label1,file2.root=label2,..."
0017 // Finds recursively all hists in all directories of the first file.
0018 // The hists of one directory are grouped in one layer of the GFHistManager.
0019 //
0020 // Following options are recognised:
0021 // 1)
0022 // If 'option' contains 'norm', the hists are normalised to their number of entries.
0023 // 2)
0024 // If 'option' contains 'skip(XYZ)' or 'skipHist(XYZ)', hists are skipped if their names
0025 // contain 'XYZ', similarly with 'skip(XYZ)' or 'skipDir(XYZ)' for directories.
0026 // Can be given several times.
0027 // 3)
0028 // If 'option' contains 'name(XYZ)' or 'nameHist(XYZ)', hists are skipped if their names
0029 // do NOT contain 'XYZ', similarly with 'name(XYZ)' or 'nameHist(XYZ)' for directories.
0030 // Can be given several times.
0031 // 4)
0032 // If 'option' contains 'sumperdir', for each directory hists created containing
0033 // the means and RMS of all (1D-)hists of that directory and puts these in the following
0034 // 'layer' of the GFHistManager.
0035 //
0036 // (Lower and upper case are ignored for 'norm', 'skip', 'name' and 'sumperdir'.)
0037 //
0038 // CAVEAT:
0039 // If you want to skip all hists that contain 'Norm' in their name by option 'skip(Norm)',
0040 // this will also lead to the normalisation option being switched on...
