Paper_columns form the top-most item parent. (The Paper_columns X parent is System, which is a spanner.)
Paper_columns form the units for the spacing engine. They are numbered, the first (leftmost) is column 0. Numbering happens before line-breaking, and columns are not renumbered after line breaking.
Since many columns go unused, you should only use the rank field to get ordering information. Two adjacent columns may have non-adjacent numbers.
Don't be confused by right-items: each spacing wish can also contain a number of items, with which a spacing constraint may be kept. It's a little baroque, but it might come in handy later on?
