// 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.
