+/**
+ * Smarty plugin
+ * -------------------------------------------------------------
+ * Type:     modifier
+ * Name:     displayUrl
+ * Purpose:  give back the display URL
+ * If the modification is preformed on a string then the (new <lib>)->getDisplayUrl method is called, (this defaults to BitPage if not specified)
+ * If the modification is preformed on an object then, if <lib> is given, then it is passed as the parameter to (new <lib>)->getDisplayUrl otherwise, the object' getDisplayUrl method is called
+ * If the modification is preformed on an array then, if <lib> is given, then it is passed as the parameter to (new <lib>)->getDisplayUrl otherwise the following is attempted:
+ *     If the array contains an element display_url it is returned
+ *     If the array contains an element content_type_guid then lib becomes the handler class of the content_type_guid and the array is passed as the parameter to (new <lib>)->getDisplayUrl
+ *     If the array contains an element handler_class then lib becomes the handler_class and the array is passed as the parameter to (new <lib>)->getDisplayUrl
+ * --
+ * If all of the above tests fail then LibertyContent::getDisplayUrl with the argument to the modifier passed as the second argument
+ * Example: {'My Page'|displayUrl}, {'admin'|displayUrl:BitUser}, {$gContent|displayUrl:MyObject}
