Add support for using documentation siphons in multiple ways
Experiental support for generating multiple output formats from the same siphoned data. Adds a contrived example to generate a plain list of all CLI commands (the "itemlist" format). Eventually we can consider moving the tempate procesisng into the Output class as well as a way to override how the data is traversed (ordered).
