0.9.0.0

The switch from Column to Field is complete. This is a small yet pervasive change. To update your code please change all usages of Column as follows:

• Column of a non-nullable type: to Field
• Column of a nullable type: to FieldNullable
• Column of a nullability-polymorphic type: to Field_ n

For example

• Column SqlText -> Field SqlText
• Column (Nullable SqlInt4) -> FieldNullable SqlInt4
• Column a -> Field_ n a

This is the only change that has been made in this version, in order to ease user transition.
