Hi Gurus, I have a class, specified in models cart.rb, which doesn't
inherit from anything--it's just a container

class Cart
...

I just discovered I can't call number_to_currency in that class.  Any
idea how to "include" it in my code?  I tried
ActionView.number_to_currency without luck.  I could kill a few lines
of non-DRY regexp code in cart.rb if I could just use
number_to_currency.

Many TIA,
Craig
