This prepares a map that can be used with MultipleComparisonAnalyzer. If the set of simulation runs does not contain the provided experiment names, then an IllegalArgumentException occurs. If there are multiple simulation runs with the same experiment name, then an IllegalArgumentException occurs. In other words, when running the experiments, the user must make the experiment names unique in order for this map to be built.
Return
a map with key exp_name containing an array of values, each value from each replication
Parameters
The set of experiment names for with the responses need extraction, must not be empty
the name of the response variable, time weighted variable or counter. If the response name is not associated with the experiment, then an empty array will be returned.
