What does this script do?

I'm trying to remove the call for
<script src="components/com_simgallery/assets/javascript/jquery.history.js" type="text/javascript"></script>

because it's causing issues with my template, without it it works fine, so I've found the code in /components/com_simgallery/helpers/simgallery.php but commenting out the line there does nothing, where does the component parses this script into the head of the template??

Thanks!
