Better local require() paths for Node.js

Problem

When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:

const Article = require('../../../../app/models/article');

Those suck for maintenance and they're ugly.

Possible solutions

#define MSDesignatedInitializer(__SEL__) __attribute__((unavailable("Invoke the designated initializer `" # __SEL__ "` instead.")))

// Sample usage:

- (instancetype)initWithObject:(id)object;
- (instancetype)init MSDesignatedInitializer(initWithObject:); // <- This even gets auto-complete.

// Now calling init on this class would throw a warning.
