Description
The following example doesn't increase the NullCount correctly in a column.
PrimitiveColumn intColumn = new PrimitiveColumn("Int", 5);
intColumn[2] - null;
Assert.True(1, intColumn.NullCount)
This occurs because we have to differentiate between initialized but unset values and set, pre-existing values.
