/**
* The main building block of a Spark application is a set of routes. A route is
* made up of three simple pieces:
*
* - A verb (get, post, put, delete, head, trace, connect, options)
* - A path (/hello, /users/:name)
* - A callback (request, response)
*
* Example:
* get("/hello", (request, response) -> {
* return "Hello World!";
* });
* The public methods and fields in this class should be statically imported for the semantic to make sense.
* Ie. one should use:
* 'post("/books")' without the prefix 'Spark.'
