/**
 * Custom Meta Box Class
 *
 * The Meta Box Class is used by including it in your plugin files and using its methods to 
 * create custom meta boxes for custom post types. It is meant to be very simple and 
 * straightforward. For name spacing purposes, All Types metabox ( meaning you can do anything with it )
 * is used. 
 *
 * This class is derived from Meta Box script by Rilwis<rilwis@gmail.com> version 3.2. which later was forked 
 * by Cory Crowley (email: cory.ivan@gmail.com) The purpose of this class is not to rewrite the script but to 
 * modify and change small things and adding a few field types that i needed to my personal preference. 
 * The original author did a great job in writing this class, so all props goes to him.
