function answers_lock_example_node_presave in Answers 7.4

Implements hook_node_presave().

When a new question is saved, if the configuration is set to lock questions, then set the question lock. Here, we could use "answers_reset_question_lock", however it is faster to simply call "answers_lock_question" to set the lock.

However, neither of those functions can be used within hook_node_insert because they call node_save, resulting in an infinite loop. So, here, we simply set the question lock field directly (generally not the best practice).

    $node->question_locks[$lang][0]['value'] = 'answers_lock_example';
