 *
 *      Class to create a folder of Histograms (TH1,TH2, TH2Poly...)
 *
 *      Each histogram-axis has associated the name of the corresponding TSVariable.
 *      Those names are to be provided when the histogram is added to the folder
 *      via the Add method.
 *
 *      Several Fill methods are provided to fill all the histograms
 *      at the same time from a given set of TSVariable values.
 *
 *
 *      Folder is the Owner of the Added Objects
