SQLSession - a rewrite

One of the problems with the SQLSession-class is that it cannot be easily integrated into a project without having to change from using $_SESSION to using the object.
As this provides an unnecessary level of inconvenience I have recoded SQLSession to use session_set_save_handler() so that, as usual, $_SESSION can be used.
As this is a complete rewrite the new version of the class is not compatible with previous releases.
The new version is now being tested and is supposed to be released soon.
