====== onMultiuserChanged() ======
wrtc.onMultiuserChanged() is an event function called when a connection has multiple users at other end and a list of those users has been received.

You can use this event to display the list.

===== Occurs =====
List of users at other end of connection received.

The IXNX voice bridge sends such a list when you connect to it, and every time the list contents change (people added/removed from list or start/end talking).

===== Arguments =====
wrtc.onMultiuserChanged(obj, list)
  * obj - call object raising the event
  * list - JSON structure containing: {type:"multi_user_info", users:[{name:..., name_dn:..., talking:...}]}
    * name - string containing user's address
    * name_dn - string containing user's display name
    * talking - string:
      * "yes" - user is currently talking
      * "no" - user is currently silent
    * audio - audio fallback:
      * "yes" - user audio is transmitted by voice bridge (voice fallback)
      * "no" - user audio not transmitted by voice bridge (normal operation)
    * webclient - is user a wrtc or SIP client:
      * "yes" - user is a wrtc client capable of multiple media streams
      * "no" - user is a SIP client not capable of multiple media streams, audio always transmitted through voice bridge
===== Return value =====
Ignored.

===== Example =====
  {type:"multi_user_info", users:[{name:"john@company.com", name_dn:"John", talking:"yes"}, {name:"eve@company.com", name_dn:"Eve", talking:"no"}]}

<code>
wrtc.onMultiuserChanged = function(obj, list) {
    for (var i = 0; i < list.users.length; i++) {
      -- display list.users[i].name, list.users[i].name_dn and list.users[i].talking --
}
</code>

===== Advanced =====
As [[ixnx:wrtc:js:api:call:adv.multiuser|call.adv.multiuser]] is set //after// wrtc.onMultiuserChanged() you can use obj.adv.multiuser to access the previous, old list of multiusers in your code (if you eg want to find what has changed).
