Luigi,

if I understand you , i think you are suggesting that for each key in the map, have the key point to an instance of a struct that contains rest of the elements in that row.

Is that right?

Keep in mind I have to do this for hundreds of lines.

Why not simply define a struct and use a map to associate a struct
