Example using HTTP and wrapping a HandlerFunc

This example illustrates wrapping a single HnadlerFunc. It is the simplest form of wrapping an HTTP handler. Though useful for wrapping individual handler functions, it quickly gets cumbersome when wrapping too many. Wrapping a handler or a muxer is much more efficient.

This example is runnable with go run main.go - it will start listening on port 8080.

Once it's running, in another window, issue a request to the /hello endpoint: curl localhost:8080/hello and you should an event appear on STDOUT in the pane running the example.
