Basic routing

It's time to extend our WebPart to support multiple routes. First, let's extract the WebPart and bind it to an identifier:

App.fs

   5: 
   6: 
   7: 

let webPart = OK "Hello World!"

startWebServer defaultConfig webPart

In C#, one would call it "assign webPart to a variable", but in functional world there's really no concept of a variable. Instead, we can "bind" a value to an identifier, which we can reuse later. Values, once bound, can't be mutated during runtime.
