-        A class for training PyTorch models.
-        Implements the training loop logic, load/save methods.
-
-        fit method - training loop logic:
-         - Calculates the predicted output for the batch using the PyTorch model.
-         - Calculates the loss between the predicted and actual output using a loss function.
-         - Computes the gradients of the loss with respect to the model's parameters using
-           backpropagation.
-         - Updates the model's parameters using an optimizer.
-
-        save method:
-         called by DataDrawer
-         - Saving any nn.Module state_dict
-         - Saving model_meta_data, this dict should contain any additional data that the
-           user needs to store. e.g class_names for classification models.
-
-        load method:
-         currently DataDrawer is responsible for the actual loading.
-         when using continual_learning the DataDrawer will load the dict
-         (saved by self.save(path)). and this class will populate the necessary
-         state_dict of the self.model & self.optimizer and self.model_meta_data.
