61	<	* The write() method takes a message, formats it using the

63	<	* using System.out.println(). The source is usually the
64	<	* calling object, referenced by `this'. The method has been
65	<	* made synchronized to avoid it being called by two different
46	<	* objects and the output ending up merged on the screen.
61	>	* The write() method takes a line of text, pre-formatted
62	>	* and outputs it using a method defined by the actual
63	>	* implementation. The verbosity is given in case the
64	>	* implementation wishes to utilise it in the layout -
65	>	* eg. a different colour or font.
66		*
67	<	* @param source A string representation of the calling object.
