- in singular wrap entry_title and byline in `<header="entry-header"></header>`
- new action hook; open_entry_header, close_entry_header in singular content.
- comments.php using <section>
- add inline docs in all hooks and functions in template files, just like oenology theme by chip bennet
  @link: http://www.chipbennett.net/themes/oenology/
  this inline docs is not for php doc block parser, but more for readability of the code.
  this is for easier development. and part of the goals for hybrid core 2.0 and the future
  Making it easy for new theme authors to learn from our code.
