/*
Catch Errors Handler
With async/await, you need some way to catch errors
Instead of using try{} catch(e) {} in each controller, we wrap the function in
catchErrors(), catch any errors they throw, and pass it along to our express middleware with
next()
*/

/*
Not Found Error Handler
If we hit a route that is not found, we mark it as 404 and pass it along to the next error handler
to display
*/

MongoDB Validation Error Handler
Detect if there are mongodb validation errors that we can nicely show via flash messages
