-"""
-This is an attempt at bridging matrix clients into a Jitis meet room via Matrix
-video call.  It uses hard-coded xml strings overg XMPP BOSH. It can display one
-of the streams from the Jitsi bridge until the second lot of SDP comes down and
-we set the remote SDP at which point the stream ends. Our video never gets to
-the bridge.
-
-Requires:
-npm install jquery jsdom

- *  A JavaScript library for XMPP BOSH.

- *  This is the JavaScript version of the Strophe library.  Since JavaScript
- *  has no facilities for persistent TCP connections, this library uses

- *  information on BOSH can be found in XEP 124.

- *  This Function object extension method creates a bound method similar

- *  <a href='https://developer.mozilla.org/en/JavaScript/Reference/Global_Objects/Function/bind'>MDC's bind() documentation</a> and

- *  for a complete explanation.
- *
- *  This extension already exists in some browsers (namely, Firefox 3), but
- *  we provide it to support those that don't.
- *
- *  Parameters:
- *    (Object) obj - The object that will become 'this' in the bound function.
- *    (Object) argN - An option argument that will be prepended to the 
- *      arguments given for the function call

- *  >     <example/>
- *  >   </query>
- *  > </iq>
- *  The corresponding DOM manipulations to get a similar fragment would be
- *  a lot more tedious and probably involve several helper variables.
- *
- *  Since adding children makes new operations operate on the child, up()
- *  is provided to traverse up the tree.  To add two children, do

-/** Class: Strophe.Connection
- *  XMPP Connection manager.

- *  Thie class is the main part of Strophe.  It manages a BOSH connection

- *  data arrives.  It supports SASL PLAIN, SASL DIGEST-MD5, and legacy
- *  authentication.
- *
- *  After creating a Strophe.Connection object, the user will typically
- *  call connect() with a user supplied callback to handle connection level
- *  events like authentication failure, disconnection, or connection
- *  complete.
- *
- *  The user will also have several event handlers defined by using
- *  addHandler() and addTimedHandler().  These will allow the user code to
- *  respond to interesting stanzas or do something periodically with the
- *  connection.  These handlers will be active once authentication is
- *  finished.
- *
- *  To send data to the connection, use send().

-     *  The handler will receive the stanza that triggered it as its argument.

-     *
-     *  As a convenience, the ns parameters applies to the top level element

-     *
-     *  The return value should be saved if you wish to remove the handler
