To all-

As the result of discussion on this list and of my own considerations, 
I've made the following changes to variant:

1) Less ambiguous recursive_variant name. That is,

   recursive_variant<...>::type

is now spelled

   make_recursive_variant<...>::type

2) MPL type sequences allowed as bounded types. Thus,

   variant< type-seq >  // no longer supported

must now be spelled

   make_variant_over< type-seq >::type

Similarly, the recursive_variant form is spelled

   make_recursive_variant_over< type-seq >::type

While some of the names are a bit longer, I feel the changes are 
beneficial to the library.

I will soon update the documentation to reflect these changes.
