Subject: Moved out the xml system again.  I think that if I am going to do it
 again, I'm going to do it over from scratch, that was just painful.  Also,
 started in again on the server system, it's looking pretty good, already got
 connections working, next up is managing data flow through clients and
 protocols!

+/**
+ * Implements xml writing in the XML standard format.  Also allows you to
+ * break that format and auto-indent your exported xml data for ease of
+ * reading.  The auto-indenting will only be applied to sections that
+ * have no content of their own already.  This means that except for
+ * whitespace all of your data will be preserved perfectly.
+ * You can create an XmlWriter object around a file, or access the static
+ * write function directly and just hand it a filename and a root XmlNode.
+ * When using an XmlWriter object the interface is identicle to that of
+ * the XmlDocument class, so reference that class for API info.  However
+ * when the initial (or root) node is closed, and the document is finished
+ * the file will be created and written to automatically.  The user can
+ * check to see if this is actually true by calling the isFinished
+ * function in the XmlDocument class.
