Add pagination to users table

We want to change the table so that only 10 or so users can be displayed at a time but we're not sure how to do this.
Create admin capabilities in users controller

We changed the set_user method so that if the current user is an admin, then they can look at all the info of other users, but if they're not admin, they cannot. Felix manually created the admin in our terminal. 

ex:
rails c
new_admin.email = '(the admin email)'
new_admin.admin = true
new_admin.password = '(the admin password)'
new_admin.password_confirmation = '(the admin password)'
new_admin.save
