/**
 * The rest server exposes similar functionality that is available via the socket.io interface.
 *
 * The main difference is that only request/response functionality is supported.
 *
 * ### Interface
 *
 * Args to a POST method are expected to be passed in a tuple of varying sizes, aka array.
 *
 * Return values from a POST or GET take on two shapes:
 *
 * #### Return value only indicating success or failure of the operation:
 *
 * ```
 * {
 *   success: boolean // set only on success
 *   err: string      // set onlhy in an error case
 * }
 * ```
 *
 * #### Return value passing along a return arg
 *
 * ```
 * {
 *   result: any      // set only on success
 *   err: string      // set onlhy in an error case
 * }
 *
 * ```
