1. Ran the first experiment on the IIMB instance matching dataset.
2. Added simple statistics for found property sets.

* [IOTW,NEW] Added the loading mechanism for the IIMB instance matching dataset.
* [IOTW,DEB] Added debug mechanism for found shared properties. We write these properties to the screen, including their statistical relevance relative to the from and to graphs.
* [IOTW,SC] Removed old/temporary code and rearranged existing predicates.
