-  Bump to 1.0
-  Add in Steve to author list

-  update main script to be ./lib/caching-proxy.js
-  when doing an npm install of this package, you can use "node start.js" to automatically fire up a standalone cache server
-  if require("caching-proxy"), you can start it up by 1) standalone require("caching-proxy").start() or 2) get a reverence to the base CachingProxy via var proxy = require("caching-proxy").CachingProxy, and then new proxy({port: 1000})
-  add a header indicating if served from cache or from a fresh request (headers['served-by'] = "CachingProxy Fresh"; or headers['served-by'] = "CachingProxy Cache";)
- rename the forever.js script to daemon.sh to accurately relect it is a shell script (not run via node forever.js, but rather ./daemon.sh)

- move start inside of the CachingProxy object as a static method
- add notes to readme
