I uploaded template traits to the vault a long time ago. You can find it 
at https://github.com/boost-vault/Miscellaneous as template_traits.zip, 
or simply 
https://github.com/boost-vault/Miscellaneous/blob/master/template_traits.zip

It works only for templates of type arguments, no non-type or template 
arguments. There were other limitations, but I no longer remember them.
