Build up specificity for nested routes.

[tjni]

When adding an array of routes, each route will increase the
specificity instead of using only that of the last route.

Resolves #102.

@tjni you are on the right track here. Specificity of a previously added route was being stomped by a second route, and using an object as a bucket avoids the stomping. However I'm not sure this restores all the functionality we need (there are definitely two tests I have added that do not pass with it) however this is a step in the right direction.

@tjni this seems an incremental fix, but fails on the following assertion:

test("Matches the route with the longer static prefix with nesting", function() {
  var handler1 = { handler: 1 };
  var handler2 = { handler: 2 };
  var router = new RouteRecognizer();

  router.add([{ path: "/", handler: handler1 }, { path: ":post_id", handler: handler1 }]);
  router.add([{ path: "/team", handler: handler2 }, { path: ":user_slug", handler: handler2 }]);

  resultsMatch(router.recognize("/team"), [
    { handler: handler2, params: { }, isDynamic: false },
    { handler: handler2, params: { }, isDynamic: false }
  ]);
});

Which I believe is appropriate to assert emberjs/ember.js#13960 is fixed.

Planning on looking into this in a few hours in the evening, unless someone else is already.

@tjni in fact the test you've added here already passes on master, I believe.

[mixonic]

scratch that, my test does not pass in 0.1.5 either. I must have incorrect ported emberjs/ember.js#13960

[mixonic]

@tjni I've confirmed you fix with this test: https://github.com/tildeio/route-recognizer/pull/105/files#diff-d4ce617de337dd77d23737176f335d8cR884 Please add it to this PR! I believe that will give us the option for moving forward with this change instead of reverting.

LGTM

This is an unnecessary type conversion which is why it was removed.

@mixonic It turns out we did need to land the test from #85.

I've extracted exactly the routes generated from emberjs/ember.js#14073 and we trigger the same failure as the test from #85.

Here is what Ember generates to feed into route-recognizer:

  router.add([{"path":"/application_loading","handler":"application_loading"}], {"as":"application_loading"});
  router.add([{"path":"/_unused_dummy_error_path_route_application/:error","handler":"application_error"}], {"as":"application_error"});
  router.add([{"path":"/","handler":"application"},{"path":"/loading","handler":"loading"}], {"as":"loading"});
  router.add([{"path":"/","handler":"application"},{"path":"/_unused_dummy_error_path_route_application/:error","handler":"error"}], {"as":"error"});
  router.add([{"path":"/","handler":"application"},{"path":"/test1_loading","handler":"test1_loading"}], {"as":"test1_loading"});
  router.add([{"path":"/","handler":"application"},{"path":"/_unused_dummy_error_path_route_test1/:error","handler":"test1_error"}], {"as":"test1_error"});
  router.add([{"path":"/","handler":"application"},{"path":"/","handler":"test1"},{"path":"/loading","handler":"test1.loading"}], {"as":"test1.loading"});
  router.add([{"path":"/","handler":"application"},{"path":"/","handler":"test1"},{"path":"/_unused_dummy_error_path_route_test1/:error","handler":"test1.error"}], {"as":"test1.error"});
  router.add([{"path":"/","handler":"application"},{"path":"/","handler":"test1"},{"path":"/test2_loading","handler":"test1.test2_loading"}], {"as":"test1.test2_loading"});
  router.add([{"path":"/","handler":"application"},{"path":"/","handler":"test1"},{"path":"/_unused_dummy_error_path_route_test2/:error","handler":"test1.test2_error"}], {"as":"test1.test2_error"});
  router.add([{"path":"/","handler":"application"},{"path":"/","handler":"test1"},{"path":"/test2","handler":"test1.test2"}], {"as":"test1.test2"});
  router.add([{"path":"/","handler":"application"},{"path":"/","handler":"test1"},{"path":"/index_loading","handler":"test1.index_loading"}], {"as":"test1.index_loading"});
  router.add([{"path":"/","handler":"application"},{"path":"/","handler":"test1"},{"path":"/_unused_dummy_error_path_route_index/:error","handler":"test1.index_error"}], {"as":"test1.index_error"});
  router.add([{"path":"/","handler":"application"},{"path":"/","handler":"test1"},{"path":"/","handler":"test1.index"}], {"as":"test1.index"});
  router.add([{"path":"/","handler":"application"},{"path":"/","handler":"test1"},{"path":"/","handler":"test1.index"}], {"as":"test1"});
  router.add([{"path":"/","handler":"application"},{"path":"/","handler":"test1"},{"path":"/","handler":"test1.index"}], {"as":"application"});
  router.add([{"path":"/","handler":"application"},{"path":"/misc_loading","handler":"misc_loading"}], {"as":"misc_loading"});
  router.add([{"path":"/","handler":"application"},{"path":"/_unused_dummy_error_path_route_misc/:error","handler":"misc_error"}], {"as":"misc_error"});
  router.add([{"path":"/","handler":"application"},{"path":"/:param","handler":"misc"}], {"as":"misc"});

The adjacent epsilon segments break things.
