      @parl.remote_class has to use this function to simplify the code.
      To create a remote object, PARL has to import the module that contains the decorated class.
      It may run some unnecessary code when importing the module, and this is why we use this function
      to simplify the code.
  
      For example.
      @parl.remote_class
      class A(object):
        def add(self, a, b):
          return a + b
      def data_process():
        XXXX
      ------------------>
      The last two lines of the above code block will be removed as they are not class-related.
