Rather than using Object.preventExtensions to throw exceptions when setting any out-of-bounds index, we must instead compromise by only throwing for the common cases, which are -1 and list.length. Having Object.keys() support is essential for List to work with React Native ListViewDataSource.
Resolves#80
The idea is that we will have an NPM module that should always be required to use the Realm JS API. It will handle the underlying implementation details depending on which environment it is being run in (i.e. JavaScriptCore, Chrome, Node).
The focus here was on stubbing out the machinery required to get React Native Chrome debugging working with the Realm API by leveraging synchronous requests. The app itself will need to run a web server that responds to these requests.
