protocol MaplyLoaderInterpreter : NSObjectProtocol
Loader Interpreter converts raw data into images and objects.
Converts data returned from a remote source (or cache) into images and/or MaplyComponentObjects that have already been added to the view (disabled).
Parse the data coming back from a remote request and turn it into something we can use.
Convert the NSData passed in to image and component objects (e.g. add stuff to the view controller). Everything added should be disabled to start.
