Will test if a user has a valid token.
Note: Script will return false if the client is offline. Check internet acces before using any GraphConnection features.
If GraphConnection returns true, GraphConnection::getUserId() will return the token principial name.
In order to request a new token, you need to proceed the following steps:
Start a web browser with the uri returned from GraphConnection::getAuthorizeUrl(login_hint).
The login_hint can be a UPN if you know the user's UPN, or "".
Check if the browser is redirected to an uri starting with the string returned by GraphConnection::getResponseUrl().
Put the redirect uri from the browser to GraphConnection::setAuthorizationResponse(string ResponseUrl).
If the call succeeds, the user received a valid token.
