OVERRIDING VALUES IN INITIALIZE

If you want to override values in initialize then you can put this in your calling class and it will let you transform one of the values:

def initialize(args)

super

@quantity = args[:quantity].to_i

end

Its not super clean, but there might be times it needs to be done.
