KHRES-320 #comment: Added the functionality desired. In the actual
implementation the session map is not deleted from memory. It means that
the algorithm takes track of a session which starts in a file and
continues in another one. The drawback is that if you delete all files
and load them again you are going to have a super estimated number of
sessions.
KHRES-320 #comment Tests for the session part
