SWE22 Template Editor

[jsmith]

This PR resolves #22 This PR resolves #7

This PR implements the template editor. An instructor can now edit their template and set seats available / closed / reserved.

To make this all work, I added several RESTful endpoints. The full list of new endpoints includes:

• GET /instructor/{courseName}/{courseSection}: This is the view page where an instructor can edit their course template
• GET /courses: Retrieves all of the courses
• POST /courses: Insert or update a course
• POST /courses/{id}/seats: Insert or delete a particular course's seats
• GET /course/{id}: Retrieve a particular course

A few things that still need to be fixed are:

• [x] Ability to save changes to the database
• [x] Some more styling
• [x] Change view url to something like this: intructor/{courseName}/{section}

Ok an instructor can now edit their templates! I'll add some comments throughout the PR

Hey @jacsmith21 , in the issue description, can you provide step by step instructions on how to view/test the changes you've made? For some reason, after I create a course and go to http://localhost:8080/courses/{course_id_here}, im just getting a JSON: {"id":1,"name":"test","rows":5,"cols":5,"seats":[]}. No grid view, and I'm not sure what I'm doing wrong :p

[jsmith]

Oh yeah sorry about that, I'll update the PR description. The reason that was happening is that I created a few RESTful endpoints for courses!

Ok now I can get to the grid view. Sweet. I do see one issue though;

When I visit http://localhost:8080/instructor/1 and go to click on a link in the course list, I get a 404 because it's trying to navigate to http://localhost:8080/instructor/courses/1

[jsmith]

Oh nice, I'll fix that bug!

@jacsmith21 Looks great! The only issue I see is that when you are in http://localhost:8080/instructor/coursename, theres no way to get back to the instructor view. Maybe make the navbar Attendance Tracker text a link to http://localhost:8080/instructor/? Once this is working, good to merge!
