/**
 * Basic XML Writer helper library. It does not do full XML Well-Formedness
 * checks, but provides basic element and attribute value escaping, and tracks
 * open tags to simplify use.
 * 

* Sampe usage: *

 * 
 * XmlWriter w = new XmlWriter();
 * w.start(DOC_TAG, "xmlns", DOC_NAMESPACE);
 * if (foo != null)
 *   w.start(FOO_TAG).value(foo).end();
 * w.end();
