Use this module to get and set messages from the librarians to a MyLibrary database.
message_global is a Boolean value. Set it to true ('1') to make this message intended for everybody. Set it to false ('2') to make it not. False is the default. Call message_global without any parameters to get it's value.
This module is legacy code. I sometimes wonder if it is even needed, and the message_global method feels like a hack.
