docs: Replies the URL of a resource.
  
  <p>You may use Unix-like syntax to write the resource path, ie.
  you may use slashes to separate filenames.
  
  <p>If the {@code classLoader} parameter is <code>null</code>,
  the class loader replied by {@link ClassLoaderFinder} is used.
  If this last is <code>null</code>, the class loader of
  the Resources class is used.
  
  @param classLoader is the research scope. If <code>null</code>,
  the class loader replied by {@link ClassLoaderFinder} is used.
  @param path is the absolute path of the resource.
  @return the url of the resource or <code>null</code> if the resource was
  not found in class paths.
