agile: backlog Improve OM's code generation marker
cmake: fix typos in eos status message
readme: add link to DCI paper

Tweeted by Luigi Ballabio, needs deeper parsing.
engine: created a switch to toggle om on or off

- sml: tagger now copies the facet properties in model (directory name
  and prefix). Without this the file names coming out of OM would be
  incorrect.
- created a flag in engine and propagate it all the way to the back
  end factory so we can switch OM on or off.
