Type Vectors (aka tuple)

Hi,

I have been using what I call a "type vector" (tv) for a while. I thought I 
would offer up my implementation to the boost gods and see if its worthy.... 
or could be made worthy.... or if bits of it might be worthy....

I see others have done similar things but called it something else (eg. 
tuples).  I have no preference as to the name and would be happy to change it.

There is a lot more that could be added to it but it already allows you to 
enumerate, filter and transform types. It also has a couple of handy 
shortcuts for creating type vectors.
