example of using Go + Echo

main.go

/*
You need to have Go installed and make sure your $GOPATH is set.
Then, install echo by running:
go get -u github.com/labstack/echo

Finally run:
go run main.go
Where main.go is this file.
It will start the server on port 8080
You can now query your server using curl:
$ curl -i localhost:8080
$ curl -i -X POST localhost:8080
