/* colibri.js -- a COLIBRI focus
* The colibri spec has been submitted to the XMPP Standards Foundation
* for publications as a XMPP extensions:
* http://xmpp.org/extensions/inbox/colibri.html
*
* colibri.js is a participating focus, i.e. the focus participates
* in the conference. The conference itself can be ad-hoc, through a
* MUC, through PubSub, etc.
*
* colibri.js relies heavily on the strophe.jingle library available
* from https://github.com/ESTOS/strophe.jingle
* and interoperates with the Jitsi videobridge available from
* https://jitsi.org/Projects/JitsiVideobridge
