title: How can I make a class global to the entire application?
body: <p>I would like to access a class everywhere in my application, how can I do this?</p>
  
  <p>To make it more clear, I have a class somewhere that use some code. I have an other class that use the same code. I do not want to duplicate so I would like to call the same code in both place by using something. In php I would just include("abc.php") in both... I do not want to create the object everytime I want to use the code.</p>
