	/// The base class for all Formatter classes.
	///
	/// A formatter basically takes a Message object
	/// and formats it into a string. How the formatting
	/// is exactly done is up to the implementation of
	/// Formatter. For example, a very simple implementation
	/// might simply take the message's Text (see getText()).
	/// A useful implementation should at least take the Message's
	/// Time, Priority and Text fields and put them into a string.
	///
	/// The Formatter class supports the Configurable
	/// interface, so the behaviour of certain formatters
	/// is configurable.
	/// 
	/// Trivial implementations of of getProperty() and 
	/// setProperty() are provided.
	///
	/// Subclasses must at least provide a format() method.
