Output clarification

[Connor-Bowley]

When I run the module, the only thing in the given output folder is a folder called logs/. In this folder I see checkpoints and stuff, but I would have expected a more obvious "here is the final output CNN". It would also be nice if in the README you talked a little bit about the output folder's setup, what there is, where to find it, and how to use the output.

Regarding the how to use the output, if there is going to be a follow on for running the trained models (which your comments on the extension index PR indicate there might be) you should mention something about that in the README.

I have updated the readme describing the structure of the output directory. Right now, the output directory holds the checkpoints and tensorboard logs. The checkpoints will be used by the user at inference time. However, right now the module doesn't have any inference module. In the future, I will develop the inference module and then the use cases of the checkpoints can be described more clearly.
