// cAuthenticator.h
// Interfaces to the cAuthenticator class representing the thread that authenticates users against the official MC server
// Authentication prevents "hackers" from joining with an arbitrary username (possibly impersonating the server admins)
// For more info, see http://wiki.vg/Session#Server_operation
// In MCS, authentication is implemented as a single thread that receives queued auth requests and dispatches them one by one.
