[WandLZhang]

current app.yaml results in following error:
ERROR: (gcloud.app.deploy) The [application] field is specified in file [/home/williszhang/waze-ccp-gcp/app.yaml]. This field is not used by gcloud and must be removed. Project name should instead be specified either by gcloud config set project MY_PROJECT or by setting the --project flag on individual command executions.

should use project-id instead of project-name

manually started cron command in order for app to work
