Feature Request: generate comment containing foreign keys

[kokizzu]

generate comment containing all foreign keys for that table, so it could be used better for programmer
example:

  struct Member {
     Id int `db:"id"`
     Name string `db:"name"`
     BillingAddressId  sql.NullInt64   `db:"billing_address_id"` // Address.id
  }
  struct Address {
    Id int `db:"id"`
    Address1 string         `db:"address_id"` 
  }
