32/// Function to fill tuples (TNtuple/TNtupleD) from
33/// a simple ASCII data file. With auto and decltype - we can
34/// get rid of DataType parameter :) (or with a simple typedef inside ntuple class).
35/// An input file consists of non-empty lines (separated by newline-characters), possibly empty lines,
36/// and comments (treated as empty lines). Each non-empty line should contain N numbers - entry for a tuple.
37/// Non-strict mode lets you to have newline-characters inside a tuple's row (as it worked
38/// in ROOT prior to v5.3xxx).
