Added prerequisites for using Continuent Hadoop Tools to README.md.
Added support for fan-in replication topologies, which the replicator
supports by writing data for each replication service to a staging
sub-directory.  Load-reduce-check now uses the correct options to generate
corresponding schema including prepending the service name to the Hive
schema name.  Fixed a bug in the MapReduce sort that caused the merge
between base table and log to add duplicate rows and also ignore some deletes.
Updated README.md to describe current behavior better.
Fixed bad -u option in example
Adding generating oozie workflow draft version.
Merge with upstream master.
