<p>A body wrapper that emits chunked responses and also supports sending Trailer headers. Note that the response body provided to initialize must have a <code>trailers</code> method that returns a hash of trailer headers, and the rack response itself should have a Trailer header listing the headers that the <code>trailers</code> method will return.</p>
