* Made it so that the tests check if it's in the same day before doing the test

* Added another expect clause to the single panel first test
* Added another test for unfiltered full panel display
* Added a test to clear intervals

* Adds initial test files to achieve 100 percent code coverage for Clock, Loading and Map
* Adds a few instanbul ignore comments above the loading ternary statement due to it being unreachable but adding to the untested lines count and to the top of the cleanPanelInfoTimes function since the argument defaults add to multiple branches and removing the defaults doesn't lower code coverage

* Excluded index.js, reportWebVitals.js, and setupTests.js from the code coverage report due to their irrelevance
* Added a React import at the top of App.js
* Added a test file for App.js called App.spec.js to just look and see if the component renders

* Added another unit test to advance timers in the app to see if the setInterval in Main changes what is displayed
* Added another expect clause to Correc time & panel name is displayed to include a check for the panel name
* Reset what is changed for the newly added unit test the unix times to what they originally were
* Updated the checks date unit test in the Clock.spec.js file to have it's test updated with the current day since it was failing for any hard text days

* Added jest.useRealtimers in the afterEach parts of tests so that it's properly cleaned up between tests
