Corrections aforementioned tutorial
Same residual problems trying to call user instead of student
Sign in / Sign out
Cleaned up students page. Added signup/ sign in links if no one is authenticated
if a user is authenticated it shows a "Welcome [their name]"  with a sign out link
in the listing of students, if the user logged matches an email it adds a table row
with links to edit and delete their profile.
Added resource for sessions
Fixes all most all my session errors now
Commit before opening issue
Its an hour before the assignment is due and I broke it.
Unable to get to the students page because of url generation error in students#index
unable to make new users as it sayus there is an unknown attribute error in the Students controller
even though I am definately telling it to look for the password field and submit it with the button
