When the private variable publishedOn is set to null , the entry is not yet ready to be published and it
is still a draft, as soon as the publish() method is invoked its value is set to the current date and, thus,
ready to be displayed. The method isOnline() is used to check whether the entry has been published
or not, while getOnlineInfo() returns information, in a human readable form, on the elapsed time
since the date of publication.
