Return the current validation error/loss (#57)
Return the current validation error/loss (#57)

Previously, the model.py script would return the minimum error/loss
that occurred during training. This isn't particularly informative
as it's possible that the minimum validation error/loss does not
correspond with the loss of the persisted model. This update prints
the loss/error for the saved model.
