title: how to overwrite rails engine files that are in the lib directory?
body: <p>I want to overwrite a file of a rails engine, but that file is in that engine's lib/rails directory.  When I take the same file and drop it in my lib/rails directory it doesn't overwrite the file.  Seems like rails handles the lib directory differently than say files that are in the app directory.  </p>
  
  <p>Also I can't place this file in the initializer folder (<a href="https://stackoverflow.com/questions/10248174/overloading-lib-files-from-gem-mounted-as-engine">per this solution</a>) as the filename is the same as an exisiting file that is needed.  What is the proper way of doing this?  </p>
