A module that
(1) allows you to mention a list of attributes in a class,
(2) provides reader methods for the attributes,
(3) allows initialization of the class via a hash argument that gives values for the attributes,
(4) overrides equals and hash method to check for field equality
attributes :value, :currency
# initializes_with :value, :currency #=> only adds the initialize method
# equality_based_on :value, :currency #=> only overrides equality methods and hash
money = Money.new(:value => 20, :currency => 'USD') #=> #<Money:0x5138e4 @value=20, @currency="USD">
money.value #=> 20
money.currency #=> "USD"
money == Money.new(:value => 20, :currency => 'USD') #=> true
