Save Felt.com rendered map features to GeoJSON feature collection

Save bookmarklet.js as a bookmarklet and on any Felt map the currently rendered features will be saved as a file features.geojson (note: some features do not render at low zoom levels)

Metro Micro API (RideCo API)

i downloaded the metro micro APK, extracted it, and then unminified the ionic JS source code, then reverse engineered these calls using my own username/password

# get a token
curl -H "Accept: application/json; version=rccmtp-2.18.0" -X POST https://api.metro-micro.net/api-token-auth/ -F "username=youremail" -F "password=yourpass"

# get geocode results
curl -H "Accept: application/json; version=rccmtp-2.18.0" -X GET "https://api.metro-micro.net/rest/geo/places/autocomplete/?value=yourtexttogeocode&session_token=$MICRO" -H "Authorization: Token $MICRO"

# get a trip/ride id
