Clojurians Log v2

After some good prodding on Twitter - I added support for custom index.js files https://github.com/vouch-opensource/krell/commit/b2dcd34e0bb5e05de0ffddf5d6a15a79e922c373

you can now supply this boilerplate - I'm assuming this should greatly simplify customizing things for Storybook, Expo whatever directly

but we also attempt to load krell_index.js now - so if this is on the classpath we'll use it - which opens the door to creating a layer over Krell that pushes the details away
