   * transformation function.
   *
   * <p>The primary audience of this method is callers of {@code transform} who don't have a {@code
   * ListenableFuture} available and do not mind repeated, lazy function evaluation.
   *
   * @param input The future to transform
   * @param function A Function to transform the results of the provided future to the results of
   *     the returned future.

// Attempts to evaluate `output`. This will only be possible if `output` doesn't
// depend on any graph inputs (this function is safe to call if this isn't the
// case though).

// If the evaluation is successful, this function returns true and `output`s
// value is returned in `result`. Otherwise returns false. An error status is
// returned if something is wrong with the graph or input. Note that this may
