[patch] Word count sample has a flawed addToMutationMap, fix
------------------------------------------------------------

                 Key: CASSANDRA-3669
                 URL: https://issues.apache.org/jira/browse/CASSANDRA-3669
             Project: Cassandra
          Issue Type: Improvement
    Affects Versions: 1.0.6
            Reporter: Dave Brosius
            Priority: Trivial
         Attachments: mutation_sample.diff

The WordCount example shows how to use client.batch_mutate, and has a helper method for building
a mutation map. While the example works properly, the example addToMutationMap is flawed in
that it won't allow adding of multiple columns to the same row, as is what is needed to perform
a 'sql like insert' operation, which is the most likely example someone learning cassandra
will want to do. Fixed the sample addToMutationMap code so that it works correctly for multi
column inserts in one 'row'.
