This module contains the
Column class, which defines a “vertical”
array of tabular data. Whereas
Row instances are independent of their
Table, columns depend on knowledge of both their position in
the parent (column name, data type) as well as the rows that contain their data.
Key method for sorting nulls correctly.

MappedSequence. They deviate from the underlying implementation in that loading of their data is deferred until it is needed.
