Refactored out routeParams to make the route class be immutable.
Merge branch 'master' of https://github.com/Danack/intahwebz-routing

* 'master' of https://github.com/Danack/intahwebz-routing:
  Added first draft of adding function check to routing.
  Made optional param work.
  Dat dynamic return type.
  Added example app temporarily. This probably ought to be in it's own project.
  Added test to start supporting null values.
