/*!  Item in the tree-view of the TopWin main
 *   panel - contains either a module, a data set
 *   (DatSet ::GetDID()) or a plotting/analysis action
 *   (TopWin ::GetPID() calling a RMain class function).
 *
 *   Use from an application calling ModuleAnalysis:
 *   (1)  Create module items with ("MAF" is the pointer to your TopWin object):
 *        ModItem *item = new ModItem(MAF->ModuleList, [module name (const char*)]);
 *   (2)  load data by creating a corresponding DatSet class object (yields pointer "DATA")
 *   (3)  enter into MA tree view with:
 *        ModItem *dataitem = MAF->DataToTree(item,DATA);
