Pull request outlining what changes DiscoveryGarden inc. had to make to the core api code to get the editor to work.  The vast majority of code changes are just endpoint url references to images. Also, abstracting out the UI Layout initialization from the editor would allow for greater control over the appearance of the writer (since accessing resize functions like writer.layout.east.onresize = function() does not appear to be accessible via the DOM). It would be nice to have the ui layout initialization available via the delegate, allowing some functionality to be overridden.
