How to use class DecisionRule

In the examples, you will find how to check whether or not 1) a condition, e.g., C1-Y, exists in a decision rule (a column in a decision table); 2)an action, e.g., A1-, exists in a decision rule; 3) two conditions are same, e.g, C-Y and C-Y are same ; 4) two actions are same, e.g. A-/, A- are not same.
