Changes

tsk39 Deletes microstories from private section view
Added functionality to allow users to delete microstories from their
private section. A new function was added to call the REST method from
the backend. The router component was added in order to redirect the
user to the private section when deleting the story. Also, a message is
shown in the private section if the story is deleted succesfully. As the
private section and the story reader view are different components, the
history state is used to communicate the message. Also, the
documentation has been generated automatically for the different
elements.
