tested code

- added simpleheader.ejs for views files that i created
- tested code for help, detailedTweet, search (should all be working)

to access these files:
localhost:3000/help
localhost:3000/search/query wherein query is whatever query you have
(will also run if you click on hashtag and through use of search box)
localhost:3000/detailedTweet > this is not linked to any part of the
site at all
