LevelsLark 1.0.1

<?

// <readme>
/*
	This is a lite version of Olark's and Intercom's functionality (without the chat part).

	It lets you get feedback from users on your site to your email.
	
	And you won't have to rely on another company anymore!

	#killyourdependencies

	You use it like this. Put this in your PHP page wherever you want the box to show up:
	
		require('feedback-popup.php');

	The JS will POST the message to your server at /feedback-popup.php, make sure the file is
	in your root for it to work.

	P.S. You need 2 dependencies, jQuery and PHPMailer
	P.S. 2. Feel free to replace the PHP with JS etc and take it.

	License: do whatever you want with this, I don't care <3333
