/**
 * Frisco theme functions and definitions
 *
 * Because Frisco is a child theme of the BuddyPress default theme, the functions.php file from bp-default will do most of the heavy-lifting for us. 
 * The purpose of the Frisco functions.php file is to add some new functions and replace other functions from bp-default.
 *
 * DO NOT EDIT THIS FILE. You could edit this file, but any changes you make will be lost when you upgrade the theme in the future.
 * Intead of editing this file, create a file called functions-custom.php in the Frisco theme folder and go to Frisco theme options in your dashboard to load the functions-custom.php file. See frisco_add_custom_functions() function down below. 
 *
 * For more information on BuddyPress child themes, see http://codex.buddypress.org/theme-development/building-a-buddypress-child-theme/.
