/**
 * Routed paths. Paths are dictionaries containing a test regex and a
 * renderer function.
 *
 * It's expected that exactly one regex will match a given path. Undefined
 * behavior results if this assumption is violated.
 *
 * the render function is provided with 3 parameters:
 * * uri (string): the URI provided by the client (path only)
 * * request (Incomming Message): instance of:
 *       https://nodejs.org/api/http.html#http_http_incomingmessage
 * * response (Server Response): instance of
 *       https://nodejs.org/api/http.html#http_class_http_serverresponse
 *
 * the render function is expected to handle all aspects of the server
 * response itself.
