Add function to obtain information about the current route

[bguiz]

See my patch: #21

What would be even more useful than just obtaining the current hash would be a function that return not just the path of the route, e.g.:

`/foo/123/bar`

... but instead return the full route information, e.g.:

 {
    hash: '/foo/123/bar',
    route: '[/foo/:fooId]/bar',
    bindings: {
        fooId: '123',
    },
 }
