Erlang-based server side component for SockJS. See:

https://github.com/sockjs/sockjs-client

for more information on SockJS.

Currently this is somewhat limited:

• Requires Misultin
• A couple of header-based things haven't been ported from the node server
• Hasn't been tested much
• Hasn't been performance-tested at all

Hopefully in future some of these restrictions will get improved.

Some useful application configuration parameters:

• sockjs_url - path to the sockjs library as seen by the client
• default: "/lib/sockjs.js"
• heartbeat_ms - milliseconds between heartbeat frames
• default: 25000
• session_close_ms - milliseconds to keep a session alive after a client connection goes away
• default: 5000
• json_impl - JSON library to use, mochijson2 or eep0018
• default: mochijson2

[Note that the tests test that you can send unicode strings containing \0. When using eep0018 you can't; it strips them out. So a few tests will fail.]
