 * The loop displays the posts and the post content.  See
 * http://codex.wordpress.org/The_Loop to understand it and
 * http://codex.wordpress.org/Template_Tags to understand
 * the tags used in it.
 *
 * This can be overridden in child themes with loop.php or
 * loop-template.php, where 'template' is the loop context
 * requested by a template. For example, loop-index.php would
 * be used if it exists and we ask for the loop with:
 * <code>get_template_part( 'loop', 'index' );</code>

    /* Start the Loop.
     *
     * In Twenty Ten we use the same loop in multiple contexts.
     * It is broken into three main parts: when we're displaying
     * posts that are in the gallery category, when we're displaying
     * posts in the asides category, and finally all other posts.
     *
     * Additionally, we sometimes check for whether we are on an
     * archive page, a search page, etc., allowing for small differences
     * in the loop on each template without actually duplicating
     * the rest of the loop that is shared.
     *
     * Without further ado, the loop:
