*/
function is_fb_event(){
$fbMeta=tribe_get_event_meta();
$verifyString="facebook-importer";
$result=true;
	if ($fbMeta['_EventOrigin']['0']==$verifyString){
		$result=true;
		return $result;
	}
	if ($fbMeta['_EventOrigin']['0']!=$verifyString){
		$result=false;
		return NULL;
	}
}

/**
*Plugin: Tribe Facebook Events Importer
*Builds a button to the original facebook event page in the event's info page
*/
function build_fb_link(){
$fbMeta=tribe_get_event_meta();
$eventID=$fbMeta['_FacebookID']['0'];
echo "<dt><div class='fb'><a href='http://facebook.com/".$eventID."' target='_BLANK'>Join event on <b>Facebook</b></a></div></dt>";
}
