code: def integrate_result(orig_expr, result, **options):
      """
      Returns the result of integrating over any unities ``(|x><x|)`` in
      the given expression. Intended for integrating over the result of
      representations in continuous bases.
  
      This function integrates over any unities that may have been
      inserted into the quantum expression and returns the result.
      It uses the interval of the Hilbert space of the basis state
      passed to it in order to figure out the limits of integration.
      The unities option must be
      specified for this to work.
  
      Note: This is mostly used internally by represent(). Examples are
      given merely to show the use cases.
  
      Parameters
      ==========
  
      orig_expr : quantum expression
          The original expression which was to be represented
  
      result: Expr
          The resulting representation that we wish to integrate over
