API
> read(cliOpts, builtinOpts)
Reads configurations from the filesystem and the env and returns a
figgy-pudding object with the configuration
values.
If cliOpts is provided, it will be merged with the returned config pudding,
shadowing any read values. These are intended as CLI-provided options. Do your
own process.argv parsing, though.
If builtinOpts.cwd is provided, it will be used instead of process.cwd() as
the starting point for config searching.
