+/**
+ * http://json-rpc.org/wiki/specification
+ * A remote method is invoked by sending a request to a remote service. The request is a single object serialized using JSON.
+ * <br>It has three properties:
+ * <ul>
+ * <li>method - A String containing the name of the method to be invoked.
+ * <li>params - An Array of objects to pass as arguments to the method.
+ * <li>id - The request id. This can be of any type. It is used to match the response with the request that it is replying to.
+ * </ul>
