(Swift 2) Avoiding Outbound Links Matching Patterns

The spider accumulates outbound links when crawling. Your program may specify any number of "avoid patterns" to prevent any link matching at least one of the wildcarded patterns from being added.

func chilkatTest() {
    let spider = CkoSpider()

    // --------------------------------------------------------------------
    // Note: The URLs in this example are no longer valid.
    // You should replace the URLs with URLs from a site of your
    // own choosing -- preferably your own site if testing.
    // (Google's Directory no longer exists.)
    // --------------------------------------------------------------------

    // First, we'll get the outbound links for a page in the
    // Google directory.  Then we'll add some avoid patterns
    // and then re-fetch, to see it work...

    spider.AddUnspidered("http://directory.google.com/Top/Recreation/Food/Cheese/")

    var success: Bool
    success = spider.CrawlNext()

    // Display the outbound links
    var i: Int
    var url: String?
    for i = 0; i <= spider.NumOutboundLinks.intValue - 1; i++ {
        print("\(spider.GetOutboundLink(i))")
    }
