Tutorial4 plots.C: errors in macro

[pbelecky]

FairRoot version: v18.6.4

Errors while running examples/simulation/Tutorial4/macros/plots.C:

$ cd examples/simulation/Tutorial4/macros
$ root plots.C
/simulation/Tutorial4/macros/plots.C:8:1: error: C++ requires a type specifier for all declarations
plots(Int_t nEvents = 1000, Int_t iout = 1, TString mcEngine = "TGeant3")
...

When I add void in front of plots() function declaration then following errors get when run macro:

$ root plots.C
...
simulation/Tutorial4/macros/plots.C:22:11: error: no member named 'AddFriend' in 'FairRunAna'
    fRun->AddFriend(RecoFile.Data());
...

Hi @pavel532,

#1212 has been merged and should fix this. Can you take a look?
