## Description
<section id='description'>
Delete one person by the person's <code>_id</code>. You should use one of the methods <code>findByIdAndRemove()</code> or <code>findOneAndRemove()</code>. They are like the previous update methods. They pass the removed document to the db. As usual, use the function argument <code>personId</code> as the search key.
