Optional primitive columns

Optional primitive columns

Optional columns allow you to set a column to a null or a None. Use them when you really want something to be optional. The outcome is that instead of a T you get an Option[T] and you can match, fold, flatMap, map on a None.

The Optional part is handled at a DSL level, it's not translated to Cassandra in any way.
