commented out Questions#new because new question is created from the index page and does not require it's own route
added ability to edit existing questions
This includes development of the Questions#edit and Questions#update methods as well as the addition of edit and delete(although delete not yet implemented) links to the index page.  A corresponding edit view was also added.
change form_for on index page to use short form syntax
updated index view with edit and delete links(delete not yet functioning)
added delete functionality

- this will be implemented in the controller after this branch is merged with one containing authentication/user controllers
