the args passed in are currently always empty for the DataEngine constructor.

perhaps the misunderstanding here is that there is only ever one instance of 
the DataEngine loaded, and that one engine hosts multiple sources of data.

information such as the to/from language should be encoded in the source name, 
e.g. "en:de:flower" (which might have as its data: "Blume"). the DataEngine 
would process these requests in sourceRequestEvent.
