Config Utilities
· Configuration Utilities.
NOTE: This module is deprecated and will be removed at the end of the
v2.x versions of the utilities. Preferred config system after that is
either to use true type-safe config with `net.morimekta.providence:providence-config`
or to use a simple JSON or YAML library or java properties files. The
semi-typesafe layered config did not really solve the problems I had
hoped it would, and in essence this was just a helper for merging maps
and getting pre-cast values out of it.
