/**
 * Class BetweenColumnCondition represents a `BETWEEN` condition where
 * values is between two columns. For example:
 *
 * ```php
 * new BetweenColumnsCondition(42, 'BETWEEN', 'min_value', 'max_value')
 * // Will be build to:
 * // 42 BETWEEN min_value AND max_value
 * ```
 *
 * And a more complex example:
 *
 * ```php
 * new BetweenColumnsCondition(
 *    new Expression('NOW()'),
 *    'NOT BETWEEN',
 *    (new Query)->select('time')->from('log')->orderBy('id ASC')->limit(1),
 *    'update_time'
 * );
 *
 * // Will be built to:
 * // NOW() NOT BETWEEN (SELECT time FROM log ORDER BY id ASC LIMIT 1) AND update_time
 * ```
