Fix missing ROOT version determination
Sorry, there are some another functions that uses RooFormulaVar::expression()
but does not take ROOT version into account.
Additional code improvement and bugfix are also implemented here. Note that the output of root-config --version
with latest ROOT is of the form X.YY.ZZ
(rather than X.YY/ZZ
), the root_checker.py
is also updated accordingly.
