// Package authz provides handlers to enable ACL, RBAC, ABAC authorization support.
// Simple Usage:
// import(
// "github.com/astaxie/beego"
// "github.com/astaxie/beego/plugins/authz"
// "github.com/casbin/casbin"
// )
//
// func main(){
// // mediate the access for every request
// beego.InsertFilter("*", beego.BeforeRouter, authz.NewAuthorizer(casbin.NewEnforcer("authz_model.conf", "authz_policy.csv")))
// beego.Run()
// }
//
//
// Advanced Usage:
//
// func main(){
// e := casbin.NewEnforcer("authz_model.conf", "")
// e.AddRoleForUser("alice", "admin")
// e.AddPolicy(...)
//
// beego.InsertFilter("*", beego.BeforeRouter, authz.NewAuthorizer(e))
// beego.Run()
