 @ref createNewAccount() To create a new account for this microblog, can use @ref Choqok::Account or a subclass of it,
 @ref createEditAccountWidget() To create a widget/dialog to show to user for create/edit account,
 @ref createMicroBlogWidget() To create a @ref MicroBlogWidget to show on MainWindow
 @ref createTimelineWidget() To create a @ref TimelineWidget to show on MicroBlogWidget
 
 Additionally should implement this functions:
 @ref createPost() @ref abortCreatePost() @ref fetchPost() @ref removePost() @ref updateTimelines() @ref profileUrl()
