Call train function

[8W9aG]

• Calls train when a class is defined in the train key in cog.yaml.

This is a breaking change, since currently it calls predict but uses the type definition of the train method.

broadly looks good; my general worry here is that this might have unexpected consequences for our existing high volume trainers (e.g. a trainer that has train but no setup).

and to be clear, this is a worry driven by paranoia as opposed to anything I see here. 😄 do we have a test somewhere that would catch an issue with that kind of trainer?

Luckily setup is always optional so I bet that this won't matter so much
