/**
 * This class exists to expose session.php's functions in a more testable way.
 *
 * Since many functions in session.php have global variables inside the function,
 * this exposes those functions through a testable facade that uses testable_factory's
 * mock global variables to modify global variables used in the functions.
 *
 * This is using the facade pattern to provide a testable "front" to the functions in sessions.php.
