1) Played a bit with crazy hillclimber, but doesn't really play ball

2) Took a first stab at cleaning up the OneLink tests, trying to rationalize them. Have too little battery to test them here though

3) Played a bit with how supply gap is computed in fixed inventories. To not much avail.

4) Had to rewrite the CascadePToPID because for some reasons it wasn't commited earlier
a little modification to the experiment to use summarystatistics
