I agree I think we need a fairly standard way to Tuple->X and X->Tuple.
But really it would just end up looking like
```java
public interface <X> TupleToX {
public X fromTuple(Tuple t);
}
public interface X XToTuple {
public Tuple toTuple(X record);
}
```
But I don't know how much code reuse there could be, because X is so
different for each library we are going to interface with.
