/**
* Load the comment template specified in $file.
*
* Will not display the comments template if not on single post or page, or if
* the post does not have comments.
*
* Uses the WordPress database object to query for the comments. The comments
* are passed through the 'comments_array' filter hook with the list of comments
* and the post ID respectively.
*
* The $file path is passed through a filter hook called, 'comments_template'
* which includes the TEMPLATEPATH and $file combined. Tries the $filtered path
* first and if it fails it will require the default comment template from the
* default theme. If either does not exist, then the WordPress process will be
* halted. It is advised for that reason, that the default theme is not deleted.
*
* @uses $withcomments Will not try to get the comments if the post has none.
