title: Zend Framework 2 custom view helpers - cross modules
body: <p>In Zend Framework 2, how can I have one view helper available to multiple modules?</p>
  
  <p>What I want is to have some general functions, like algorithmic functions, that can be reused by multiple modules.</p>
  
  <p>I'm currently on ZF 2 2.0.3</p>
  
  <p>Thanks.</p>
