NullPointerException in matrix vector multiplication in TimesSquaredJob
-----------------------------------------------------------------------

                 URL: https://issues.apache.org/jira/browse/MAHOUT-819

          Issue Type: Bug
          Components: Math

TimesSquaredMapper causes a NullPointerException in method close() if member out isn't initiated.
Adding a null-check fixes the issue.
