 Widgets became much more extensible when we introduced the WP_Widget class
 in version 2.8.  New widgets were easier to make, and we finally had the
 ability to create multi-instance widgets without a lot of coding overhead
 and headaches.

 Meta Boxes are used by themes and plug-ins in a similar fashion to
 customize the layout and functionality of the post/page/custom-post-type
 edit screen.  Unfortunately, the code for creating a new meta box and
 handling the subsequent form submission is difficult to track down, prone
 to errors, and nearly impossible to use in a multi-instance situation.

 We should abstract the meta box creation process so that adding a new meta
 box is as easy as adding a new widget - just extend a WP_Meta_Box class to
 add the functionality.
