I wonder if there is a way to read in CSV files so that
- certain fields within each record (line) are ignored, i.e.
   not converted to columns in the output data frame
- factors/levels are created automatically: often, the possible
   labels are known in advance and could immediately be
   converted. This would save a lot of memory and time for
   bigger files, I assume.
