This script will destroy all files created by the corresponding 
script/generate command. For instance, script/destroy migration CreatePost
will delete the appropriate ###_create_post.rb file in db/migrate, while 
script/destroy scaffold Post will delete the posts controller and 
views, post model and migration, all associated tests, and the map.resources
:posts line in config/routes.rb.
