+// Package auth provides handlers to enable basic auth support.
+// Simple Usage:

+//		"github.com/astaxie/beego"
+//		"github.com/astaxie/beego/plugins/auth"
+//	)
+//
+//	func main(){
+//		// authenticate every request
+//		beego.InsertFilter("*", beego.BeforeRouter,auth.Basic("username","secretpassword"))
+//		beego.Run()
+//	}
+//
+//
+// Advanced Usage:
+//
+//	func SecretAuth(username, password string) bool {
+//		return username == "astaxie" && password == "helloBeego"
+//	}
+//	authPlugin := auth.NewBasicAuthenticator(SecretAuth, "Authorization Required")
