tst_discover_better_experimental_model.py fails sometimes.
This is due to discover_better_experimental_model producing two different solutions.
The two corresponding origin vectors are:
"origin": [ -208.507324496093, 209.20518907699287, -266.11 ]
"origin": [ -208.50831812992388, 209.20211805759828, -266.11 ]
The remainder of the optimized_datablock.json is identical.

TODO: I don't know if both of these are legitimate, or if
this is a bug in discover_better_experimental_model.
