RE: [boost] Named template parameters

Another variation on the named template parameters.

Instead of using :: to separate the parameters, we stick with the more
traditional comma. This requires some "type wrapper" classes, each with a
name corresponding to the template parameter.

 boost::iterator_adaptor<int*, default_iterator_policies,
    Category<std::input_iterator_tag>, Reference<int>
 >

I then use a technique to turn the list of type wrappers into a
inheritance chain where each level in the chain adds a typedef such as
value_type or iterator_category. The "top" of the chain contains the
defaults. The code isn't all that complicated. I've attached it to this
email.

Cheers,
Jeremy
