dry_train and dry_eval?

[buus2]

I propose to exchange:

• dry_run train_mode=False by dry_eval,
• dry_run train_mode=True by dry_train.

In this way, the user could consciously choose if:

• he/she wants to only evaluate results from in-house solution to quickly check if everything (including paths to solutions and data) is set correctly,
• he/she wants to spend a lot of time to re-train the in-house solution and save it in his/her favourite path.

Also, after these exchanges the readmes should become more understandable.

Alternatively, I propose to exchange train_mode with only_eval/eval_only.

I like the idea of two options.

It is changed now, waiting for PR to merge.
