{ This demo shows how to use Tags of items.                                    }
{ Each item has associated integer value - Tag. Tags are used to store         }
{ additional information, which RichView does not display and does not use.    }
{------------------------------------------------------------------------------}
{ All Add*** methods (except from obsolete ones) has Add***Tag version.        }
{ Add***(...) == Add***Tag(...,0) (Tags=0 by default)                          }
{ For example, look AddNLTag and AddHotpotExTag in this demo.                  }
{ Tag of item can be obtained with GetItemTag method (or Get***Info methods)   }
{ and modified with SetItemTag (or Set***Info methods).                        }
