/**
 * This is the first loaded framework file
 * 
 * Wpv_Framework does the following (in this order):
 *  - sets constants for the frequently used paths
 *  - loads translations
 *  - loads the plugins bundled with the theme
 *  - loads some functions and helpers used in various places
 *  - sets the custom post types
 *  - loads the shortcode library for the framework
 *  - if this is wp-admin, load admin files
 * 
 * This class also loads the custom widgets and sets what the theme supports (+ custom menus)
