org.purefn.kurosawa.config
Fetch configuration from the environment.
Presently, config is stored statefully in an atom after initial load.

default-configclj
(default-config)This is our default, precendence based, load config from environment mechasnism. A deep merge is used to create final config map.
Current precendence is:
- Environemt variables
- AWS S3
- The filesystem (legacy)
Ultimately we shouldn't need this, the config stage of application/development startup needs to revisited. But until all of our components' constructors are refactored this isn't possible.
When that day comes we can remove the use of eval, the atom, and move to
a stateless startup sequence, where each component recieves the entire config map and
parses out the piece it's interested in.

fetch-s3clj
(fetch-s3)This does some nasty things to avoid a hard dependency on aws.s3 in this project.
Consider this docstring an apology. default-config shouldn't exist as such.

set!clj
(set! m)Set the config-map atom to configuration sourced from the envinronment,
probably from:
