	// In order to keep your tasklist secure for just yourself I would suggest adding a small
	// layer of security to this file. Perhaps a password. Remove the /* and */ below to activate
	// a password that has to be available in the GET-parameters of the request:
	/*
		$iCal_password = "myUnh4ck4bl3_password";
		if($_GET['pass'] != $iCal_password)
		{
			die("iCal is currently unavailable");
		}
	*/
	// By using the above security to this fill, you should add the ical to your agenda using the URL:
	//	http://www.yourdomain.com/folder-to-wrapper/ical.php?pass=myUnh4ck4ble_password

	// Login Credits
	// This file should be removed if you use it yourself
	// Change $wlUser and $wlPass on line 15 to your own login data
	// Or create a "credits.php" file outside the github folder containing both variables
	// A future release will have this option inside the Wunderlist API Wrapper, for now it's meant to be used quickly
