[undertow-dev] Docs for templates

[Greg Hellings]

Oliver,

I found it very difficult to work with the PathTemplateHandler and its
set of matching operations seemed very minimal to me. I also found no
efficient way to mix-and-match between full Paths and PathTemplate
entries. So I created my own handler class that gave the ability to
match based on both HTTP Verb and various path components.

https://github.com/greg-hellings/gully/blob/master/src/main/java/com/thehellings/gully/PlainRouter.java

I haven't used it extensively, but in my own local testing it seems to
work exactly the way I wanted - it's still just an HttpHandler
underneath, so it can be placed anywhere in a handler chain. And it
operates on the result of getRelativePath, so you can nest them within
each other, or place them within other components in a handler chain
and the class should operate properly.

The whole set of handler and its dependent classes should be available
as a Maven artifact if you want to play with it. If this sort of
functionality exists somewhere in core Undertow, I've been entirely
unable to decipher it and locate its functioning.
