City names are now disambiguated by a two-letter country code. This commit handles almost everything needed to make this transition. Main next steps are fixing up map edits automatically and making the city picker UI understand the extra level of hierarchy. A little bit of fallout: lakeslice gridlocks again; this regression is actually from the recent traffic signal changes, but I'm just now regenerating everything. Will fix soon.

# This example runs the same scenario repeatedly, each time cancelling a
|
|
# different number of trips uniformly at random. The eventual goal is to
|
|
# quantify how many trips need to be cancelled to substantially speed up
|
|
# remaining ones.
|
|
#
|
|
# Before running this script, start the API server:
|
|
#
|
|
# > cargo run --release --bin headless -- --port=1234 --alerts=silence
|
|
#
|
|
# You may need to install https://requests.readthedocs.io
|
|
# Keep this script formatted with autopep8 -i
