Kendo UI Widget Problem

Hi!
I have read this article and I'm wondering where can I find "Utils" Class to Add JQ and CSS. 
Can You help me with this?

It's prob part of the source that article was based on which lives here blog.falafel.com/.../Using_Kendo_with_Sitefinity_-_Part_1_-_Kendo_PanelBar

However the link to the code seems borked :/  Might want to hit them up on that

:( I've wrote to them, maybe they will fix it soon Thx for reply!
