Add the "Back to top" button why not us jquery from joomla

Hi,

when you want to us the Add the "Back to top" button in your documentation link http://t3-framework.org/documentation/bs3-customization#back-to-top
you install a new jquery.easing.1.3.js is it possible to use the jquery from joomla and is that not easier because joomla already installed jquery 1.10
and do not get conflicts with other js.

Regards
