[WIP] Implement support for secondary index reads

16:07:27 +gwicke I think you might want to inverse the
loop
16:07:53 +gwicke instead of looping over the returned
attributes, you probably want to pull out the index
attributes for the data table
16:08:48 +gwicke and you might want to check which otherattributes were asked for in proj (if it's not all)
16:09:05 +gwicke and then add those in newReq.proj
