Quizzer::Element::Noninteractive::Note -- noninteractive note Element

This is a noninteractive note Element. Notes are generally some important peice of information that you want the user to see sometime. Since we are running non-interactively, we can't pause to show them. Instead, they are saved to root's mailbox.

The show method mails the note to root if the note has not been displayed before. The external unix mail program is used to do this, if it is present.
