Precedence is in the order of paramters outcome_space > issues > outcomes.
If neither is given, a ValueError exception will be raised.
Will not copy the outcome-space if it is given
A CartesianOutcomeSpace will be created if an outcome-space is not given
If outcomes is given or all issues are discrete, a DiscreteCartesianOutcomeSpace will be created
