Exports the variable $LoggedOn_user_id

The error reported is that $LoggedOn_user_id is not exported by manageusrs.

The short test program does not display that error.

In my program on the defining side of the interface boundary, I declare our $LoggedOn_user_id = 0; so there clearly should be something to export.

And later I populate the variable with the desired data 

    my $username1 = $session->param("user_id");
    warn("username1 : '$username1'");
    $LoggedOn_user_id = $username1;  
    warn("Already logged on LoggedOn_user_id : '$LoggedOn_user_id'");

And at that point, the desired information is in the variable.
