title: Cross controller variables in Phalcon
body: <p>In an effort to keep my code DRY I would like to be able to define "cross controller" variables.</p>
  
  <p>Classic example is that I would like access to some config items that are loaded in my bootstap.</p>
  
  <p>What is the best practise method of achieving this?</p>
