Demo example doesn't work

[LLCampos]

Version 0.21.0.

If I copy/paste this demo to a sbt project I get the following error:

object ui is not a member of package com.http4s.rho.swagger

Edit: Code in the tutorial also seems to be broken...

You'll need to add the rho-swagger and rho-swagger-ui artifacts as dependencies.
