Vinyl adapter for the file system

 A Vinyl adapter simply exposes a `src(globs)` and a `dest(folder)` method.
 Each return a stream. The `src` stream produces Vinyl objects, and the `dest`
 stream consumes Vinyl objects. Vinyl adapters can expose extra methods that
 might be specific to their input/output medium, such as the `symlink` method
 `vinyl-fs` provides.
