aah, I hadn't understood what you were asking for.

Yes, I'll make sure that the headers include all the other headers that they 
need, so that if you only use basic vector stuff you only have to 
#include<vector.h>. Just like in Eigen 1. You won't have to #include manually 
the internal headers that deal with expression templates, etc.

But as you suggest, it's also possible to go further and provide an optional 
meta-header including a whole bunch of headers at once. That would be useful 
to get a quick start, for drafts, tutorials, etc. But of course it's not 
optimal to include more than what's necessary (at least, it slows down 
compilation) so this meta header can only be an option. Just like what Qt 
does, #include<QtGui> includes all the headers of the QtGui module.
