title: How does Zend\Db in ZF2 control transactions?
body: <p>The ZF1 Zend_Db reference manual has an <a href="http://framework.zend.com/manual/1.12/en/zend.db.adapter.html#zend.db.adapter.transactions">entire section</a> on performing transactions.</p>
  
  <p>The <a href="http://framework.zend.com/manual/2.0/en/modules/zend.db.adapter.html">ZF2 Zend\Db reference manual</a> lacks any documentation on transactions.</p>
  
  <p>How do I perform transactions in ZF2?  Example code would be helpful.</p>
