 * The useResource hook allows you to GET and PUT the state of

 *
 * Example call:
 *
 * <pre>
 *   const {
 *     loading,
 *     error,
 *     resourceState,
 *     setResourceState,
 *     submit

 * </pre>
 *
 * Returned properties:
 *
 * * loading - will be true as long as the result is still being fetched from
 *             the server.
 * * error - Will be null or an error object.
 * * resourceState - A state object. The `.data` property of this object will
 *                   contain the parsed JSON from the server.
 * * setResourceState - Update the local cache of the resource.
 * * submit - Send a PUT request to the server.
 *
 * If you don't need the full resourceState, you can also use the `data` and
 * `setData` properties instead of `resourceState` or `useResourceState`.
