fix require issue in example file
get fancy working on latest rbx (2.2.6)
code cleanup
Start on getting fdoc working on latest rbx (2.2.6)

Rubinius changed some internal APIs while targeting
Ruby >= 2.0
E.g. a method definition no longer returns a Method object but instead the name of the method as a Symbol (adopting this feature from MRI).
This causes most of our fdoc documentation tool to not work anymore. Need to fix this.
Tests that aren't working right now, are commented out.
