wsd-caveman-chat: A websocket-driver, caveman2, chat example

This common lisp project is an example of using websockets to create a browser based chat. In particular, it is a proof of concept using the first two libraries.

• websocket-driver: websocket server (using clack) in common lisp. This project ignores the websocket client side.
• caveman2: web framework that uses clack as the web-server front end and djula as the html template engine. This example uses hunchentoot as the web-server backend. This example ignores the DB part of caveman.
• event-emitter: used in websocket-driver but also used to control the chat room.
• jonathan: to encode and decode JSON on the server side
• parenscript: to generate browser side javascript including browser side websocket client.
• log4cl: to generate logging information to understand what is going on.
• string-case: fast case for strings
• alexandria: utilities
