If i use the RowMapper here, i would have to execute 2X the queries. The query i execute here, retrieve all the povertyLines info + the likelihood info ( which is the same for each row ). for each row a create a povertyLine object.  Then i create a povertyLineLikelihood object using the list of povertyLine Object + the likelihood info i got from the same query. I can not do all this with one rawMapper (query)
