[Html-widget] Nested fieldsets: first steps

[Michael Gray]

Nearly there.  I'll do patches against svn once 1.08 is out, but 
meanwhile:

 http://www2.eng.cam.ac.uk/~mjg17/perl/HTML-Widget-1.07_svn54_BLE_01.tar.gz

Have a look at:

 t/element_block.t
 t/09nested_embed.t

 HTML::Widget::Element::Block
 HTML::Widget::Element::Fieldset

 HTML::Widget - embed, merge, find_elements

and my previous message

I probably need to write a summary of the changes from a package user's
perspective, and one from a package developer's prospective.  

Best
