Assignment edit page is now an upload page

However, it is not unique for every assignment, it is the same upload page for all assignments which are all stored in the public folder. Working on fixing this so each assignment edit page has a separate upload page
Uploaded file location changed

Uploaded assignment files are now stored as storage/system/uploads/:id/file_name.ext
Updated seeds and routes files

seeds.rb adds more than 1 assignment so I can test uploads for different assignments. And the whiteboard.com/uploads/ route is no longer available on the website since the upload page only appears for individual assignments
Removing the upload route broke things
Route changes

Working on making the route to access an assignment look like the following

http://localhost:3000/courses/1/sections/1/assignments/1

where the 1s represent the ID of each field. Not having the id would simply list all of the assignments/sections/courses.
This sucks
