title: Extend class from Pod library
body: <p>In my project I'm subclassing an existing class from a pod library because I don't want to change the pod source file directly so I can update the library in the future. The problem is that the method I'm overriding is making use of another method in a different class that has been declared as internal so it only can be called from classes within its own module.</p>
  
  <p>Is there an easy solution for this? Can I add my new created class to the existing module?</p>
