//This function would make the user enter a queue and it uses a callback to handle the user's state.
//When the user gets his turn he may get a QueueITToken which signifies the user's session.
//An error would be sent to the callback if:
// 1) Queue-it's servers can't be reached (connectivity issue).
// 2) SSL connection error if custom queue domain is used having an invalid certificate.
// 3) Client receives HTTP 4xx response.
// In all these cases is most likely a misconfiguration of the queue settings:
// Invalid customer ID, event alias ID or cname setting on queue (GO Queue-it portal -> event settings).
