ProcessedItemList mention in 08_data_block.ipynb

Whilst reading through the 08_data_block.ipynb I noticed this sentence:

We also define a ProcessedItemList with an obj method that can get the unprocessed items: for instance a processed label will be an index between 0 and the number of classes - 1, the corresponding obj will be the name of the class. The first one is needed by the model for the training, but the second one is better for displaying the objects.

But in the code itself ProcessedItemList seems to have disappeared. I understand that this class is in the videos ( but in the current version of the notebook this class in not there any longer.

Would it make sense to remove the sentence above from
