The default screen name is displayed. It can be edited for now, but this will be changed soon.
Incorporated the post title.

Screen name will default to the name of the user, and this can't be changed.
The post title is shown in the view that is seen by the admin when he/she is moderating
a blog post.
[completed] The blog view. All the posts that are marked as approved can be seen on the URL.

For now, the status is given as 1, because there are no posts that have been marked as 3, but this will be changed before merging into master
[cleanup] Removed all the unnecessary echo statements inside the blog controller
Removed the model file for the blog view. Although, before writing this module, I belived
that a differnet model will be required, I realised that the code from the
admin portal model can be reused, and I have reused that code.
Removed the var_dump statement in the footer.html file, which was there for debugging purposes.
Added a link to the blog in the header file
In the query that fetches all the posts from the DB, added the order by postid DESC condition. So that the latest posts are always on the top.
Elaborated the data that is given in case the file that the system is looking for is not found.
Changed the default controller from the authentication controller to the blog controller
Heavily redesigned the header file.

Now, depending on whether the user is logged in or not, the login or the logour button is showed. 

Further if the user is logged out then instead (Username is logged in) nothing is shown.

Also, fixed an issue due to which any user who was not logged in and came to blogcont was infinitely redirected to the same page again and again.
Added a debugging statement at the top of the blog view file to show the number of posts that were fetched from the database.
Replaced the manual header redirect performed, with the inbuilt function redirect in the URL helper.
[change-in-design] Instead of defining the location in the session (which would mean that only users who had logged in would be able to use the data in that) stored the post location in the constants file inside the config/ folder.
Removed the declaration for the post location in the session userdata array
Replaced $this->session->userdata('postloc') with the constant defined in the config/constant.php file 'POSTS_LCOATION'
Posts with status 3 are shown. (This was set to 1 for testing purposes before)
Changed blog portal to create together, until the final name of the application
is decided
Changed blog portal to create together, until the final name of the application
is decided. Also, fixed a semicolon error in auth.php
