        // 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 READONLY_DB of the app.  This is necessary
        // if records are being saved, but not committed to the db, yet should be included
        // in the lookup window.
