/**
 * BP-Default theme functions and definitions
 *
 * Sets up the theme and provides some helper functions. Some helper functions
 * are used in the theme as custom template tags. Others are attached to action and
 * filter hooks in WordPress and BuddyPress to change core functionality.
 *
 * The first function, bp_dtheme_setup(), sets up the theme by registering support
 * for various features in WordPress, such as post thumbnails and navigation menus, and
 * for BuddyPress, action buttons and javascript localisation.
 *
 * When using a child theme (see http://codex.wordpress.org/Theme_Development, http://codex.wordpress.org/Child_Themes
 * and http://codex.buddypress.org/theme-development/building-a-buddypress-child-theme/), you can override
 * certain functions (those wrapped in a function_exists() call) by defining them first in your
 * child theme's functions.php file. The child theme's functions.php file is included before the
 * parent theme's file, so the child theme functions would be used.
 *
 * Functions that are not pluggable (not wrapped in function_exists()) are instead attached
 * to a filter or action hook. The hook can be removed by using remove_action() or
 * remove_filter() and you can attach your own function to the hook.
 *
 * For more information on hooks, actions, and filters, see http://codex.wordpress.org/Plugin_API.
