// externalLinks()
// DESCRIPTION: XHTML Strict pop-up links (the standard compliant way)
//
// This function is based on that provided by SitePoint in the article:
// http://www.sitepoint.com/article/standards-compliant-world
// It has been modified to better support the REL attribute, as the original
// function did not allow space seperated values. This one does.
// It has also been extended to show you how you might create sized, positioned
// pop-ups
//
// To use the file you must include the following inside you XHTML's
//
//
//
// I have included two default values you can use for the REL attribute; as
// follows:
//
// pop-up
// this will open a new window 560px by 560px.
//
//
// this will open a new window 400px by 300px.
//
// You can extend this function by defining your own values for use in the REL
// attribute and defining appropriate actions for that value.
// You can also delete all the comments so it all loads faster ;)
