A simple wrapper creating a data.table object with a single column name.
.node_constructor(names = character(), sort = FALSE)A data.table object with a single column name.
Character vector of node names.
Logical indicating whether to sort the node names.
The reason this exists is so if changes should be made in the future, it is
easy to simply change this constructor, rather than changing the calls to
data.table all over the place.
