Merge remote-tracking branch 'origin/master'
Tried searchBar in Users and Carts but too complicated because the DataListViewController is fairly complex
Added another UIsearchBar in the New Request view for carts. It is not pulling all Carts, but I’ll modify it to show only carts with status as available
Committing
Added Login validation
Merge remote-tracking branch 'origin/arugg003'

Conflicts:
