Improve Base Model Naming

[chadlagore]

Our current base model (cnn) could be named better. Which makes me think, perhaps we could use a naming convention. Something like:

<model-type>-<number-of-base-layers>-<number-of-transfer-layers>

So this model would become cnn-1-2.

Seems like a sensible naming convention to me!

How about we do <model-type>-<number-of-base-layers>-<number-of-transfer-layers>-<user-id>? Seems like quite a few people want to add their own models.

It would be nice to capture the model architecture uniquely somehow in the name—perhaps Keras provides such a checksum? I haven't been able to find it in their API 😞
