TLegendEntry(TObject* obj, const char* label, Option_t* option ) :TAttText(12,0,1,0,0), TAttLine(1,1,1), TAttFill(0,0), TAttMarker(1,21,1)

   label is the text that will describe the entry, it is displayed using
   TLatex, so may have a complex format.
   option may have values
    L draw line associated w/ TAttLine if obj inherits from TAttLine
    P draw polymarker assoc. w/ TAttMarker if obj inherits from TAttMarker
    F draw a box with fill associated w/ TAttFill if obj inherits TAttFill
   default is object = "LPF"

TLegendEntry( const TLegendEntry &entry ) : TObject(entry), TAttText(entry), TAttLine(entry), TAttFill(entry), TAttMarker(entry)
