> I've made a modification to the piggy bank MutliStorage class that allows to optionally specify the index of the field in each tuple to write to output.
> This feature allows to have records with metadata like seqno, time of upload etc, and then to combine files from these records into one but without the metadata.
> e.g. 
> 1: date type seq1 data
> 2:  date type seq2 data
> then write output grouped by type and ordered by sequence:
> data
> data
