moving onto users#show
designed the 3 steps
change routes of videos and common_apps to be nested
completing the controllers for commons_apps and videos with updates
made the correct_user helper also work for nested attributes routes. Tested out common_apps
updated videos, need to make 100% sure update and create are working
making links work for steps, made a root_path_helper for the main logo at the top. Essentially the helper redirects to root_url if the user is not signed in, otherwise it goes to current_user.
made all steps linked
