/*


The exmaple below shows how to create a metabox with three fields in it that is displayed in the
create/edit post admin screens for the 'badge' and 'post' post types.



Make sure you're activated the CMB2 plugin, or used code similar to this to make sure CMB2 is being loaded:

if ( file_exists( dirname( __FILE__ ) . '/cmb2/init.php' ) ) {
	require_once dirname( __FILE__ ) . '/cmb2/init.php';
} elseif ( file_exists( dirname( __FILE__ ) . '/CMB2/init.php' ) ) {
	require_once dirname( __FILE__ ) . '/CMB2/init.php';
}
