Comprehensive HTTP Router

Here is a partial solution to Issue #202, at least for different HTTP methods.  There is no provision for websocket or SSE support here.  This is more or less a port of the excellent Vert.x RouteMatcher for RxNetty.  I do want to point out that I had to force queryParameters to be mutable on HttpRequest for this particular implementation.
I was looking at it from a list of criterion + request handler tuple. Then you can apply these patterns  on a request in the order in which they are added and delegate it to the first pattern that matches. Am I missing something here?
