Expand description

A simplified Handler trait that can react to GET requests and will render to a fmt::Write object with blockwise backing.

Anything that implements it (which includes plain &str, for example) can be packed into a SimpleRendered to form a Handler.

For binary data, render_bytes can be implemented instead of render, and utilize the WindowedInfinityWithETag’s write_bytes method (multiple times, if so desired). In that case, the render function can be left unimplemented.
