Unexpected behaviour when simulating multiple configurations

When adding multiple configuration objects to the global cadCAD configs list, the results are unexpected. I'm sure it relates to this statement in the docs:

As of now it does not support multi - system model simulation because configurations are still appended globally despite append_config being a method of Experiment.

At the end of the above notebook, I calculated the expected number of rows, if A/B testing was possible. This is also related to issue #247 (comment) I believe.

The previous release was returning partial results therefore a benchmark at this time is unwarranted
A/B tested for future release

           self.assertEqual(record_count_0_4_24 > record_count_0_4_23, True, "Invalid Row Count for current version")
