When calling
ROOT::RDataFrame df{"dataset", "filename.root"};
auto columnNames = df.GetColumnNames();
The user gets the fully expanded list of all column names. This includes all data members at all nesting levels in case a field has a complex class as its type.
It would be desirable in certain scenarios to be able to access only the list of top-level fields, e.g. when specifying the list of column names to a Snapshot call.
