Instread of having a separate format to maintain, you could simply read a
tuple-1 and then unwrap the type. That way you would only need the function in
DataSet
```
public <X> DataSet<X> readBasicTypeFile(String filePath, Class<X>
typeClass) {
return readCsv(filePath).types(typeClass).map(new Unwrapper());
}
```
You would loose control over the data source though, because the returned
type is the map operator.
