//1. Function to fill tuples (TNtuple/TNtupleD) from
//a simple ASCII data file. With auto and decltype - we can
//get rid of DataType parameter :) (or with a simple typedef inside ntuple class).
//An input file consists of non-empty lines (separated by newline-characters), possibly empty lines,
//and comments (treated as empty lines). Each non-empty line should contain N numbers - entry for a tuple.
//Non-strict mode lets you to have newline-characters inside a tuple's row (as it worked
//in ROOT prior to v5.3xxx).
