04. Progress notes

03/03/2021 - added gifts controller. Linkage between that and lists needs fixing, as 4 tests are currently failing. Also, can't currently add a gift to a list, or display gifts. One gift added to list directly via tableplus, for display purposes.
01/07/2021 - fixed non-gift-related tests, upgraded ruby version to 2.7.1 in gem file, added ability to add and delete a gift from a list
05/07/2021 - added link to return to /lists to nav bar, added welcome blurb on root page, some styling
06/07/2021 - replaced Travis CI with Github Actions for CI - using this article to help me get set up. Updated website logo.
