Experiment manager broken

[jmmcd]

The experiment manager is broken. I think there is some fragile code, eg manually adding to paths, and when scripts was moved inside src it got broken. I don't really use the experiment manager so I don't know enough to fix this.

$ python experiment_manager.py --population_size 10 --generations 3 --dataset_train ../../datasets/Vladislavleva4/Train.txt --grammar ../../grammars/supervised_learning/Vladislavleva4.bnf --experiment_name Test --runs 2
