+ * Package Detail Page Canonical URL Fix

+ * canonical URL for that page, we need to override the rel='canonical' value in the page header.
+ *
+ * The code below checks if we're on a package detail page and if so returns the package slug so that
+ * can be added to the URL. The matching apply_filters is in the main plugin in setup/frontHooks.php.
