+/**
+ * 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.
