InferenceEngine.Add a list of interventions to an InferenceEngine, using a list composed by the two following vectors:
intervention.varsvector of the variables we manipulate;
intervention.valsvector of values for the variables in observed.vars in the corresponding position.
interventions(x) <- value# S4 method for InferenceEngine
interventions(x) <- value
an InferenceEngine.
the list of interventions of the InferenceEngine.
An intervention can be applied only when building an InferenceEngine.
In case of multiple interventions of the same variable, the last intervention is the one used.
