Echo JS 0.11.0

Proxies, getters/setters and deep freeze - probably all of these can be used to emulate immutability to a certain extent :)

That's what this does ...

Makes sense because mewts are immutable!

Interesting Idea to use proxy.  I'd let others know IE11 is not compatible with this library.

Thanks! Re: IE11, I will be using BrowserStack to test across browsers soon, so will add the results to the readme!

Interesting...  may well play around with this, getting ready to add immutable to a React project.
