/**
 * Plugin Name: Entry Views
 * Plugin URI:  http://themehybrid.com/plugins/entry-views
 * Description: A WordPress plugin for tracking the number of post views.
 * Version:     1.0.0
 * Author:      Justin Tadlock
 * Author URI:  http://justintadlock.com
 * Text Domain: entry-views
 * Domain Path: /languages
 *
 * Entry views is a script for calculating the number of views a post gets.  It is meant to be basic and 
 * not a full-featured solution.  The idea is to allow theme/plugin authors to quickly load this file and 
 * build functions on top of it to suit their project needs.  This is an AJAX-based solution, so only visitors 
 * to your site with JavaScript enabled in their browser will update the view count.  It is possible to do this
 * without AJAX but not recommend (see notes below).
 *
 * Not using AJAX: You can call up ev_set_post_view_count() at any time and pass it a post ID to update the 
 * count, but this has problems.  Any links with rel="next" or rel="prefetch" will cause some browsers to prefetch
 * the data for that particular page.  This can cause the view count to be skewed.  To try and avoid this 
 * issue, you need to disable/remove adjacent_posts_rel_link_wp_head().  However, this is not bullet-proof 
 * as it cannot control links it doesn't know about.
