code: @Nullable
    public static String getClassFromPath (@Nullable final String sPath)
    {
      return sPath == null ? null : StringHelper.replaceMultipleAsString (sPath, new char [] { '\\', '/' }, '.');
    }
docs: Get the class name of the passed path. The class name is retrieved by
  replacing all path separators (\ and /) with dots (.). This method does not
  handle the file extension, so it's up to the caller to skip of any file
  extension!
  
  @param sPath
  The path to be converted. May be <code>null</code>.
  @return The class name.
