/** File: strophe.js
* A JavaScript library for XMPP BOSH/XMPP over Websocket.
*
* This is the JavaScript version of the Strophe library. Since JavaScript
* had no facilities for persistent TCP connections, this library uses
* Bidirectional-streams Over Synchronous HTTP (BOSH) to emulate
* a persistent, stateful, two-way connection to an XMPP server. More
* information on BOSH can be found in XEP 124.
*
* This version of Strophe also works with WebSockets.
* For more information on XMPP-over WebSocket see this RFC:
* http://tools.ietf.org/html/rfc7395
