Because sometimes you want a namespace for methods, but there's no
class that can be instantiated:

module Cupid
  def self.createConnection( person1, person2 )
    # ...mysterious details here...
  end
end

Cupid.createConnection( ... )


These may also be utility methods used by 'instance' methods in a
module that will be mixed into one or more other classes.
