/*

highlightImages_over * common/js/highlight.js
|

* Behaviour-abstracted highligher modul
|

*
|
||||
* Usage:
|
||||
* - include <script src="/common/js/highlight.js"></script> in the header of your file
|
||||
* - set the class of the container to "highlight". The class will have ' over' appended to it on mouseover
|
||||
* - set the overSrc attribute on any images inside that, if you want them to be changed
