<?php
/**
 *
 * content*.php
 *
 * The post format template. You can change the structure of your posts or add/remove post elements here.
 * 
 * 'id' - post id
 * 'class' - post class
 * 'thumbnail' - post icon
 * 'title' - post title
 * 'before' - post header metadata
 * 'content' - post content
 * 'after' - post footer metadata
 * 
 * To create a new custom post format template you must create a file "content-YourTemplateName.php"
 * Then copy the contents of the existing content.php into your file and edit it the way you want.
 * 
 * Change an existing get_template_part() function as follows:
 * get_template_part('content', 'YourTemplateName');
 *
