[boost] [typeof] template template parameters, etc.

Hi all, The typeof submission has been updated to include the latest features, most notably support for *template template parameters*. Please take it in the in the Boost sandbox file vault, http://boost-sandbox.sourceforge.net/vault/ (typeof.zip). (Most credit for the template template parameters support goes to Peder). Among other additions are support for enum template parameters, and reused template parameters, such as in: template<class T, T n> class x; Also the REGISTER_TEMPLATE_X macro has been eliminated. Instead, the REGISTER_TEMPLATE macro has been "overloaded" to cover all the cases of template registration. Please see the documentation for more details. Regards, Arkadiy
