This function returns a table containing the data provided by a Facebook User Access Token:

• appId — String representing the Facebook App ID that you receive when you register your app.

• declinedPermissions — Table containing permissions that the user has denied through the app or through Facebook's app settings.

• expiration — Number that corresponds to the date/time when the Facebook login token expires.

• grantedPermissions — Table containing permissions that the user has granted to the app.

• lastRefreshed — Number that corresponds to the last date/time when the Facebook login token was refreshed.

• token — String representing the access token used by Facebook to represent the current user.
