		// This is a generic lookup constructor that will work with any table and any column.
		// It extends the capabilites of the lookup dialog in the following ways:
		//
		//	1) 2 columns rather than one
		// 2) The ability to select DISTINCT column values
		//
		// Only set distinctValues equal to true if necessary.  In many cases, the constraints
		// of the index(es) will enforce this uniqueness.  Selecting DISTINCT does require
		// overhead by the database to ensure that all values returned are distinct.  Therefore,
		// use this ONLY when you need it.
		//
		// For complicated queries, you can pass in the sql select statement.  This would be
		// necessary if joins are involved since by default both columns must come from the
		// same table.
		//
		// If you do query by sql statement, you must pass in the maximum length of column1,
		// since it cannot be derived when you query using your own sql statement.
		//
		// The optional database connection can be used if you'd like the lookup class
		// to use a database pointer other than the global READONLY_DB.  This is necessary if
		// records are being saved, but not committed to the db, yet should be included
		// in the lookup window.
