void DetachRes

(

res

)

Auxiliary templated functions If the user lambda returns a TH1F*, TTree*, TEventList*, we incur in the problem of that object being automatically owned by the current open file.

For these three types, we call SetDirectory(nullptr) to detach the returned object from the file we are reading the TTree from. Note: the only sane case in which this should happen is when a TH1F* is returned.
