ManyToMany Controller

Hi, first of all thank you for the amazing library.

My situation is the following:

• User entity

export class User {
  // ...
  @ManyToMany(type => Document, document => document.users)
  @JoinTable()
  documents: Document[];
}

• Document entity

export class Document {
  // ...
  @ManyToMany(type => User, user => user.documents)
  users: User[];
}

The code above generates a third table (obviously) with userId and documentId. Is there a way to create a controller that exposes “nested endpoints” and that automatically handles this type of relationship (with filters, etc.)?

For example:

• GET /users/:id/documents - retrieves specific user documents
• POST /users/:id/documents - creates the new document and also populates the intermediate table

Partially related to https://github.com/nestjsx/crud/issues/239 …which could be taken into account. Features to handle ManyToMany relations and their “middleman” table (ordering, custom fields) would be a powerful addition.

@acepace do you have an example somewhere on how you have it working with the “owning” side?
