api.siibra_api_config

This module houses the configuration of siibra-api.

This should be the only place where user can influence the configuration of siibra-api.

As siibra-api will attempt to load this module, user can either configure siibra-api with environment variables, or overwrite the this file directly (with docker volume mount, for example).
