//Refactoring needed: Things to refactor:

• Add middleware to check instructor/client ID is there
• Make the classes name not unique [primary key pairing]
• Get Category name instead of id returned by doing another join for when you get classes by instructor id
• make the default text for the date field in Classes table be “YYY-MM-DD”
• Check if the instructor ID exists in the system before GET instructor/:id/classes
• Make it such that instructor 1 can’t delete instructor 2’s shit
• Combine client + instructor Login and do roles
