Created a module called 'model', which will contain some key transformation stuff
Switched the 'binary' class to use a more general function when it's sent across the network
Improved the 'get all binaries' functionality, which now uses the new to_json() function I wrote to make it consistent with retrieving a single record
Moved the 'workspace' model onto the new format
Made the new to_json/all_to_json interface more customizable by using a generic params Hash
Cleaned up the all_to_json() function a bit
