rest-graph 2.0.1

A lightweight Facebook Graph API client We have moved the development from rest-graph to [rest-core][]. By now on, we would only fix bugs in rest-graph rather than adding features, and we would only backport important changes from rest-core once in a period. If you want the latest goodies, please see [rest-core][] Otherwise, you can stay with rest-graph with bugs fixes. [rest-core]: https://github.com/cardinalblue/rest-core
