+ Composing Routers
+Routers expose both their routes and options via the Router protocol, enabling one to create new routers from existing ones.
Adding routes to an existing routers
+Let's define a router in an Atom:
(require '[reitit.core :as r])
+
+(def router (atom (r/router
+ [["/foo/bar" identity]
+ ["/foo/bar/:id" identity]])))
+
+(r/routes @router)
+;[["/foo/bar" {:handler #object[clojure.core$identity]}]
+; ["/foo/bar/:id" {:handler #object[clojure.core$identity]}]]
+A helper to add new route to a router:
+(defn add-route [router route]
+ (r/router
+ (conj (r/routes router) route)
+ (r/options router)))
+Now, we can add routers to the router:
+(swap! router add-route ["/foo/bar/:id/:subid" identity])
+
+(r/routes @router)
+;[["/foo/bar" {:handler #object[clojure.core$identity]}]
+; ["/foo/bar/:id" {:handler #object[clojure.core$identity]}]
+; ["/foo/bar/:id/:subid" {:handler #object[clojure.core$identity]}]]
+Router is recreated, so all the rules are fires:
+(swap! router add-route ["/foo/:fail" identity])
+;CompilerException clojure.lang.ExceptionInfo: Router contains conflicting routes:
+;
+; /foo/bar
+;-> /foo/:fail
+Merging routers
+Given we have two routers:
+(def r1 (r/router ["/route1" identity]))
+(def r2 (r/router ["/route2" identity]))
+We can create a new router, with merged routes and options:
+(def r12 (r/router
+ (merge
+ (r/routes r1)
+ (r/routes r2))
+ (merge
+ (r/options r1)
+ (r/options r2))))
+
+(r/routes r12)
+;[["/route1" {:handler #object[clojure.core$identity]}]
+; ["/route2" {:handler #object[clojure.core$identity]}]]
