NAME
    SelectSaver - save and restore selected file handle

SYNOPSIS
        use SelectSaver;

        {
           my $saver = SelectSaver->new(FILEHANDLE);
           # FILEHANDLE is selected
        }
        # previous handle is selected

        {
           my $saver = SelectSaver->new;
           # new handle may be selected, or not
        }
        # previous handle is selected

DESCRIPTION
    A "SelectSaver" object contains a reference to the file handle that was selected when it was
    created. If its "new" method gets an extra parameter, then that parameter is selected;
    otherwise, the selected file handle remains unchanged.

    When a "SelectSaver" is destroyed, it re-selects the file handle that was selected when it was
    created.
