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