# RootController
#
# This controller exists solely to handle requests to `root_url`. When a user is
# logged in and has customized their `dashboard` setting, they will be
# redirected to their preferred location.
#
# For users who haven't customized the setting, we simply delegate to
# `DashboardController#show`, which is the default.
