Serveable simplifies creating a [Rack][rack] mountable site. It contains a
`Site` module and an `Item` module. These can be mixed into classes that expose
the correct interface to turn them into easy Rack-fodder.
See [`example/simple.rb`](examples/simple.rb) for a basic implementation.
## That interface you speak of...
A `Site` must implement the following:
- `#each(&block)`, which enumerates `Item` type objects.
An `Item` must implement the following:
- `#contents`, that returns the contents;
- `#url`, that returns the full url to serve at.
