ea199e33 23/// \class AliMUONObjectPair
24///
25/// The equivalent of a std::pair<TObject*,TObject*> ;-)
26///
27/// What else can be said ? That if we'd been using STL, that class
28/// would not be there, thus saving some octets ? No comment.
29///
30/// Well, in fact, there *is* a difference wrt to std::pair : here
31/// we decide on the ownership of the first and/or second object...
