Piggybank MutliStorage - specify field to write in output

                 Key: PIG-1237
                 URL: https://issues.apache.org/jira/browse/PIG-1237
             Project: Pig
          Issue Type: Improvement

to combine files from these records into one but without the metadata.
1: date type seq1 data
2:  date type seq2 data

then write output grouped by type and ordered by sequence:
