-"""
-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

- *  for a complete explanation.
- *
- *  This extension already exists in some browsers (namely, Firefox 3), but

- *
- *  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

-/** Class: Strophe.Builder
- *  XML DOM builder.
- *
- *  This object provides an interface similar to JQuery but for building
- *  DOM element easily and rapidly.  All the functions except for toString()
- *  and tree() return the object, so calls can be chained.  Here's an
- *  example using the $iq() builder helper.
- *  > $iq({to: 'you', from: 'me', type: 'get', id: '1'})
- *  >     .c('query', {xmlns: 'strophe:example'})
- *  >     .c('example')
- *  >     .toString()
- *  The above generates this XML fragment
- *  > <iq to='you' from='me' type='get' id='1'>
- *  >   <query xmlns='strophe:example'>
- *  >     <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
- *  > builder.c('child1', ...).up().c('child2', ...)
- *  The next operation on the Builder will be relative to the second child.
