RemarksThis class also manages the life time of all opened datasessions
When it detects that a datasession for a thread is no longer needed (because the thread has stopped) then it will close that datasession and all tables that are opened by it.
At application shutdown it will also close all opened datasessions including private datasessions that could be opened by forms or reports.
