-A site groups together the three functions necesary to make an application:
-
-* A function to convert from the URL type to path segments.
-
-* A function to convert from path segments to the URL, if possible.
-
-* A function to return the application for a given URL.
-
-There are two type parameters for Site: the first is the URL datatype, the
-second is the application datatype. The application datatype will depend upon
-your server backend.
