To fire up the Go server, some environment variables need to be set:
TANDY_PUBLIC_ROOT must be an absolute path to the public/ folder containing the Tandygram assets.
TANDY_TIEDOT_DIR must be an absolute path to a directory where the Tiedot database will be created. The directory specified will be created if it doesn't exist.
TANDY_HTTP_PORT is optional, and allows specification of port to serve from. If not specified or not parsable it defaults to 8080.
