Write unit test to validate that parameter interventions actually worked

sophisticated interventions may only trigger on certain variables that are created on the fly. Thus confirming that a variable was intervened on is not completely trivial, so a test function should be created to validate a specific intervention

@djinnome , what functional interventions is this referring to? Currently, PyCIEMSS only supports interventions on parameters.

The need for a unit test to confirm that a functional intervention actually worked is the same as the need for a unit test to confirm that a parameter intervention actually worked.
