Current behavior

The Router interface uses UrlMatcher and UrlMatcher is not exported.

Expected behavior

The UrlMatcher should be exported as well. We have documentation for it but leads to a 404.

What is the motivation / use case for changing the behavior?

I am a member of the docs team and we get an issue every other week about the UrlMatcher link here leading to a 404.

There are a few issues in this repo, a few issues on aio repo. I decided to investigate the issue with @petebacondarwin to see if that was a dgeni issue and we discovered (well, he did) that dgeni is not parsing out the UrlMatcher documentation which exist here because at the end, the UrlMatcher is not exported with the barrel.

I am in no position to assert that it should be public or not, but we can't document it otherwise, so it would be better to decide in make it public or remove the link from the API since we cannot document it (and I think we shouldn't if it is not public).
