# Use as
Cursor.new(Model.includes(foos: [:bar], :foo_bars).where(id < 1000000)).find_each do |model|
  # do something
end

# Inspired by https://github.com/afair/postgresql_cursor

upstream myapp_puma {
  server unix:/tmp/myapp_puma.sock fail_timeout=0;

# for redirecting to https version of the site

l.call("foo") # => Hi foo!

      # self.instance_variable_set("@#{attribute_name}", attribute_value)

      ##### Method two #####
      # Manually creates methods for both getter and setter and then
