- Change in Match.java: Empty match represents all packets (universal set) while empty set is the null match.
So, in case of no intersection, return a null Match.
intersect() and getIntersection() optimized in case of universal and empty sets
- Changes in MatchTest.java to junit the above changes
- Change in FlowEntry.java: Match.mergewithFilter() is now returning a new Match instance
