/**
* Format for Discourse Tool
* <p/>
* Original code by <A HREF="http://usuarios.iponet.es/imoreta">owd</A>.
* Revised and updated for revision 0108 by Ben Fry (10 March 2006).
* This code may later be moved to its own 'Tool' plugin, but is included
* with release 0108+ while features for the "Tools" menu are in testing.
* <p/>
* Updated for 0122 to simply copy the code directly to the clipboard,
* rather than opening a new window.
* <p/>
* Updated for 0144 to only format the selected lines.
* <p/>
* Notes from the original source:
* Discourse.java This is a dirty-mix source.
* NOTE that: No macs and no keyboard. Unreliable source.
* Only format processing code using fontMetrics.
* It works under my windows XP + PentiumIV + Processing 0091.
