16 Contains information about tables specific to one class and
17 version. It provides names of table for that class. For each version of
18 class not more than two tables can exists. Normal table has typically
19 name like TH1_ver4 and additional table has name like TH1_raw4.
20 List of this objects are kept by TSQLFile class.
