  * Important - modelClass must have a public method "attributeTypes"
  * Example:
  *
  * public function attributeTypes()
  * {
  *      return [
  *          'id' => Schema::TYPE_PK,
  *          'owner_id' => Schema::TYPE_INTEGER,
  *          'name' => Schema::TYPE_STRING,
  *          'description' => Schema::TYPE_TEXT,
  *          'status' => Schema::TYPE_SMALLINT,
  *          'updated_at' => Schema::TYPE_TIMESTAMP,
  *          'created_at' => Schema::TYPE_DATETIME,
  *      ];
  * }
  *
  * Example of use:
  *
  * (new DbSync([
  *     'common\models\', // if namespace equivalent to path
  *     'Path to directory' => 'someName\models\',
  * ]))->run();
