Student directory has password protection (using sessions), checkbox delete form (although I still need to figure out how to include multiple ids in a variable in  a way that sql will read. Right now they only way I know how to delete multiple items is by doing a loop). Also, realized that GET requests are best for searches, so that user doesn't get error when going to search URL (like /search).
took out code from previous Directory that worked in terminal. It's about 140 lines of Ruby now. It could be probably be brought down if I knew how to reuse html snippets (like formsor a search bar) in multiple spots.
