Saved courses and local history in Catalog

[Jdyn]

Currently when no course is selected, there is a lot of empty space that could be filled.

Proposition

When no course is selected, display two lists:

• Previously viewed courses on this device (Local Storage)
• Saved courses of currently logged in user

Clicking on any course in either list will take the user to the corresponding CatalogView in the catalog.

Work is being done in saved branch

Tasks

• Modify the current CatalogView to allow the user to close the current course to return back to the lists.
• Hook into the saved courses of the user and display them on the page
• Design the appearance of the layout and list design
• Implement a localStorage structure that will be saved to whenever a user views a new course
  • The save implementation should ensure the course has not already been saved
  • There should be a limit of maybe 20 localStorage saved courses and then begin to overwrite probably using LIFO?
