/**
   * Provides tools for making, routing, adapting, and decorating
   * Q-JSGI web applications.
   *
   * Duck Types
   * ----------
   *
   * A Q-JSGI _app_ is a function that accepts a request and returns a
   * response.  The response may be promised.
   *
   * A Q-JSGI _request_ is an object or a promise for an object that has
   * the following properties:
   *
   * * `method` is the HTTP request method as a string.
   * * `path` is a string, guaranteed to start with `"/"`.
   * * `headers` is an object mapping lower-case HTTP headers to
   *   their corresponding values as strings.
   * * `body` is a Q-JSGI content body.
   *
   * A Q-JSGI _response_ is an object or a promise for an object that
   * has the following properties:
   *
   * * `status` is the HTTP response status code as a number.
   * * `headers` is an object mapping lower-case HTTP headers to their
   *   corresponding values as strings.
   * * `body` is a Q-JSGI content body.
   *
   * A Q-JSGI response and request content _body_ can be as simple as an
   * array of strings.  It can be a promise.  In general, it must be an
   * object that has a `forEach` method.  The `forEach` method accepts a
   * `write` function.  It goes without saying that `forEach` returns
   * `undefined`, but it can return a promise for `undefined` that will
   * resolve when it has made all of its `write` calls and the request
   * or response can be closed, re-used, or kept alive..  The `forEach`
   * function may call `write` with a `String` any number of times.  The
   * `String` may be promised.
