[undertow-dev] Docs for templates

[Bill O'Neil]

I did something similar to Greg by delegating to a RoutingHandler which has
a PathHandler fallback.

https://gist.github.com/billoneil/08b1648a3b2a849e02c57e133bd6d45c

This allows me to add prefix routes but still not flexible enough for all
uses cases. The main drawback with this approach is the prefix handler
doesn't route based on Verb but it has worked for all of my use cases so
far.

I would also like to know if there is a way the RoutingHandler can be
extended to have wildcard functionality.
