This is very valuable feedback! Thank you so much. I will remove protected attributes. I have thought about deletion and dependents and so forth I just wasn't sure how to address it yet. I must admit, I have completely ignored tests, thinking that I would write them later, but perhaps this is the wrong approach. As for indentations, they show properly on my end in Sublime, I will have to see why they appear differently in the repo. Again, really great feedback, I may take you up on a further discussion.
