Class PyjamasExternalProxy

Create a JSON remote service object. The url is the URL that will 
receive POST data with the JSON request. See the JSON-RPC spec for 
more information.

The handler object should implement 
    onRemoteResponse(value, requestInfo)
to accept the return value of the remote method, and
    onRemoteError(code, error_dict, requestInfo)
         code = http-code or 0
         error_dict is an jsonrpc 2.0 error dict:
             {
               'code': jsonrpc-error-code (integer) ,
               'message': jsonrpc-error-message (string) ,
               'data' : extra-error-data
             }
to handle errors.
