+  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()

+  return fn(req, res, next).catch(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
+*/
+exports.notFound = (req, res, next) => {
+  const err = new Error('This route does not exists');
+  err.status = 404;
