Column statistics (min/max, values) for an in-memory table.

These are constructed with the rows attribute and a list each for columns for which you want min/max and the values present. Note that None in min/max indicates no non-None values were found. An empty set in values indicates that all values were None.

This then exposes a dictionary interface
