methods won't work without add() first being
called.

 * `Rack::insert_after($target, $name, $file = null)` — Same as `Rack::insert_before()`, except new middleware is inserted after `$target`.
 * `Rack::swap($target, $name, $file = null)` — Replace `$target` middleware with `$name`.
-* `Rack::init($middleware = array())` — Can optionally be used as a simpler way to start Rack, as it takes an array of strings representing the stack classes. It also starts output buffering, so anything echoed within a stack class, will not be output till after Rack has output it's headers. Is also automatically called to start output buffering if needed the first time you call `Rack::add()`, `Rack::insert_before()`, or `Rack::insert_after()`.

 * `Rack::run()` — Initiate and execute the Rack stack.
