/**
 * This class constructs an {@link IDataSet} given a directory containing control
 * files. It handles translations of "null"(the string), into null.
 * 
 * Example usage:
 * 
 * File ctlDir = new File("src/sqlloader");
 * File orderedTablesFile = new File("src/sqlloader/tables.lst");
 * IDataSet dataSet = new SqlLoaderControlDataSet(ctlDir, orderedTablesFile);
 * 
 * The file orderedTablesFile must contain the names of the tables to
 * be imported. As a convention the .ctl file must have the same name as the table names file.
 * Here an example of the "tables.lst" file:
 * 

 * 
 * 
 * LANGUAGE
COUNTRY
 * The ctlDir directory must then contain the files COUNTRY.ctl
 * and LANGUAGE.ctl.
