Private Sessions: Store sessions in a private directory or database

This class can be used as session handler to store session data in private directories or in a MySQL database table, instead of the default system temporary directory.

When using a MySQL database table as a container for the session data, the class takes care of opening the database connections and perform the SQL queries as needed. It can also create the database table to store the session data.

When using a private directory as a container for the session data, the class takes care of opening, reading and writing to the session files as needed.
