Jmafoster1/dag evaluation

[jmafoster1]

Closes #393 #399 #391 #387.

• Removes the MetamorphicRelation class in favour of generating causal tests directly.
• Improved to_dict methods for easier serialisation.
• Improved "generate and run tests" pipeline from DAG
• Added EVALUATE command to evaluate a causal DAG against a dataset.

Codecov isn't happy here because the codebase has got smaller. I have removed quite a lot of code, and thus the tests that previously covered that code. If you try to inspect the difference in coverage, it says "No Files covered by tests were changed". Hopefully this will go away once #395 is in.
