// There is a conflict between the stylish select .js and jquery tabs
// jQuery tabs uses $.inArray() which uses Array.prototype.indexOf (if its defined, not sure why they are doing this...as its a bit dangerous)
// "stylish select" has an incompatible implementation of indexOf and causes jQuery tabs to choke in IE.
// So, we can use these functions to temporaily remove the reference to indexOf - which causes jQuery to fallback and use a for each loop in $.inArray()
