svn commit: r1081607 - /hbase/branches/0.90/src/main/java/org/apache/hadoop/hbase/util/Pair.java

New Revision: 1081607

URL: http://svn.apache.org/viewvc?rev=1081607&view=rev
Log:
Add factory pattern to Pair so template types can be inferred from input
params.  Importing so HBASE-3448 (RegionSplitter) can cleanly apply.
