ABOUT
========================================================
The Google Analytics Spider is the result of a bunch of extra needs from Google Analytics that just aren't included. The script adds more robust link tracking, form field tracking, form submission, manual file skipping and the list continues to grow.

Note: Make sure you update your uacode with the correct Google Analytics code.

Usage:
<script type="text/javascript" src="./GAS.js"></script>
<script type="text/javascript">
	var my_gas = new GAS('UA-XXXXXXXX-X');
	my_gas.pump();
</script>
