TODO: Document using Responses

While you may sometimes want to respond to a request by writing directly back to the client, more often that not it is preferable to buffer your response. You can never tell how successful a request is going to be from the start, or whether an exception is going to be throw. Being able to rewrite your response at any time is a requirement for real-world applications.

The library provides the response class to make buffering your response simpler.

	Tip
	If you're keen to use HTML templates, consider looking at the stencil class, which uses Google's cTemplate library to allow you to write maintainable Model-View-Controller apps. This class is just a lightweight wrapper over cTemplate and is currently experimental.
