go slow and steady.

optimise for few dependencies and short compilation times.

we do not need to be super fast or feature-rich.

 - write getter, setter and unsetter for flash messages
   - from rocket docs
     - A “removal” cookie is a cookie that has the same name as the original cookie but has an empty value, a max-age of 0, and an expiration date far in the past.
   - use Response::with_additional_header() method to set cookie
