Added the security features in updateSearch, updateCalling and editProfiles.

Now, only student members can edit the profile of an alumni. Coordinators can't edit the profile.

The status functions have been made almost private. Before executing they will check the allotment and that the user who is logged in is a student member. And then execute the function.
Merge pull request #24 from icyflame/fix-edit-profile-privileges

updateSearch and updateCalling are not public anymore.
Added the body margin file. Included this file in all new views that will be created.
populated the coordinator controller and view.
Introduced the concept of alias across the application.

Right now, it has been implemented in the database display.

Now, hopefully, by changing a couple of variables, the alias view can be implemented easily.
