//
// Sample 1: Logon
//
// the first act of business before being able to use steamkit2's features is to
// logon to the steam network
//
// interaction with steamkit is done through client message handlers and the results
// come back through a callback queue controlled by a steamclient instance 
//
// this sample will introduce the 1st of two primary ways of handling callbacks: the inline loop
// 
// do note however, that this method isn't preferred, and the method introduced in
// Sample 2 should be used
