Subject: [PATCH] add eslint rules from fbjs
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Summary: As @​zpao suggested (reference #58) here is the new PR with the rules from [facebook/fbjs#49](https://github.com/facebook/fbjs/pull/49).

I'll still need some guidance on what should be Relay specific.

At the moment with the current fbjs rules there is a lot of errors on [no-undef](http://eslint.org/docs/rules/no-undef.html) (example: $FlowIssue, $FixMe, $Enum and also when defining Flow types, this is related to [babel-eslint/known-issues](https://github.com/babel/babel-eslint#known-issues) - [babel-eslint#130](https://github.com/babel/babel-eslint/issues/130) and [babel-eslint#132](https://github.com/babel/babel-eslint/issues/132))

@​josephsavona @​zpao what are your thoughts?
Closes https://github.com/facebook/relay/pull/202
