/**
 *Equal value judgment is performed by ignoring the order of two Lists, ignoring null, and ignoring duplicates.
 *
 *-Use the following methods of ArList
 *    equals(List<T> list0,List<T> list1,ArSeq arSeq,ArNull arNull,ArDuplicate arDup)
 *
 *・ Ignore order is ArSeq.Specify IGNORE.ArSeq if not ignored.NOT_Specify IGNORE.
 *・ Ignore null is ArNull.Specify IGNORE.ArNull if not ignored.NOT_Specify IGNORE.
 *・ Ignore duplicates is ArDuplicate.Specify IGNORE.ArDuplicate if not ignored.NOT_Specify IGNORE.
 *
 *-In this sample, I specified to ignore separately, but it is OK even if they are mixed.
