consolidate rows on the BPR

@czue 
The lists are the rows for the final report - so if two rows have the same account number they represent the same woman, so we join them.  The values will be the case properties like the woman's name, husband's name, bank, and so forth.  Everything that's not an int should be identical between the two rows.  (The int values will be payment amounts).  It's of course possible to get unclean data, but the project expects that there's one woman per account number, so I'm not sure if it's worth checking for and resolving a conflict, especially because I'm not sure there's much we could do in the way of resolution there.
