customized for FeatureID handling.
An experimental method for doing FIDs. I'd like to see it and
AttributeReader extend a similar base. Perhaps BaseReader or something?
And perhaps have FeatureReader extend it too? This reader just returns an
incrementing index. May be sufficient for files, representing rows in a
file. For jdbc datasources another fid reader should be used.
We could have FIDReader implement AttributeReader, but it doesn't seem to
make sense, as the getAttributeType doesn't make much sense, as our
featureID is just a string. Or we could consider having a special FID
attribute in our hierarchy.
