// Usage notes:
//		The fields in a column set are order-dependent, and must match the order of the fields in
//		the query used to generate the data. The code that reads values doesn't do any fancy
//		name-matching and will copy values to incorrect locations silently if there is a
//		disagreement between the fields in the query and the fields in the column set.
//
// Examples:
//		// This is broken.
//		query	  = "SELECT * FROM Items";
//		columnSet = CSET_12_COL( CSchItem, individual_field_names );
//
//		// This is fixed.
//		query	  = "SELECT * FROM Items";
//		columnSet = CSET_FULL( ... );
