The API is still pretty new and needs some serious cleaning up on the backend but should be
reasonably functional. There are no error codes yet, 


General structure:
http://localhost:8181 + HTTP_ROOT + /api?apikey=$apikey&cmd=$command

Data returned in json format. If executing a command like "delArtist" or "addArtist" you'll get back an "OK", else, you'll get the data you requested
