auto_sequence (was auto_vector)

I've uploaded an initial version of auto_sequence to 

  http://groups.yahoo.com/group/boost/files/auto_sequence.zip

This follows Dave Abrahams's suggestion of turning my auto_vector
into a container adapter.  

You can use it like this (oh for typedef templates):

  boost::auto_deque<foo>::type x;
  boost::auto_list<foo>::type y;
  boost::auto_vector<foo>::type z;

Which are equivalent to

  boost::auto_sequence< std::deque<foo*> > x;
  boost::auto_sequence< std::list<foo*> > y;
  boost::auto_sequence< std::vector<foo*> > z;

If you have some other sequence you wish to use, you could use

  boost::auto_sequence< my_nifty_sequence<foo*> > w;

I've gone for the simple/unsafe approach of allowing you to modify
the contained values:

    z[0] = new foo;  // Whoops - memory leak.

so Don't Do That.  Personally I've never accidentally done this in
many years of using similar "auto" containers so I don't think it 
is a problem.  If anyone has strong opinions on whether there is 
a better alternative, please speak up.

Please let me know if you think this, or something close to it,
is worthy of documentation and submission.

Thanks
