Happening now tab on student end

[pulkitvyas08]

On the home screen of the student end, they should be able to see what quiz is happening right now or will happen soon, what assignment is due in the next 2-3 days, if their teacher has added an assignment then that should be displayed too
The design of the tab is not finalized yet and suggestions are welcome but as a starting point it could just be a notification box with circular scrolling notifications - hovering on them would change the color and clicking on them would open a page/modal with detailed information about them
