title: extract superclass from multiple classes and derive from it
body: <p>I want to refactor multiple classes that I think should derive from one base class.</p>
  
  <p>How to properly accomplish this refactoring using ReSharper 6 ? I can extract superclass from one of the classes, but what next? Do I have to manually then derive from this base class and search for same members in every class I want to be derived?</p>
