// = DESCRIPTION
// This program demonstrates creation of new POAs, as children of the root POA or the
// existing POA.
// There are five new POA created in this example.
// The hierarchy of POAs looks like this.
//
// /-->first_poa-->first_poa/second_poa
// RootPOA--
// \-->third_poa-->third_poa/fourth_poa-->third_poa/fourth_poa/fifth_poa
