Looking good, made some suggestions on returning ProblemTypes enum instead.

Also, we should revert the line break deletions, as they're updating the docs and making things look funky.

@bchen1116 looks good!

Could you add something about this to the user guide? We should show it off because its cool :) I suggest right before this paragraph in the AutoML guide.

Other than that, looks great! I left a few comments. @angela97lin beat me to it on most of them 😂 Your unit tests are great.
