code: private function normalizeRules(){
      	foreach($this->rules as $scope => $rules){
      		foreach($rules as $field => $rule){
      			if(is_array($rule)){
      				$this->rules[$scope][$field] = implode('|', $rule);
      			}
      		}
      	}
      }
docs: turn rules array into string based to make it much easier to proccess, must be done to make building scope rules easier
