adding basic changing password functionality
Added a link on top of front page to link to user profile page. Still not complete yet for the actual profile page.
Made changes on models.py, views.py, urls.py, and html files under templates folder so that when user clicks on the username, user will be redirected to a page where user can edit and view the user profile. Next step is to modify the html page so that each field is reviewed whether editable or not. This change only ensures the click goes to right page and links are understood.
completed profile page except minor error handling of email address
add few more files whose names are changed
redo profile branch.
