Overall:

1. Added initial skeleton from create react app that we can evolve from
2. Instead of writing generator for file by file, added generator for directory, this should allow us to skip a lot of overhead in code
3. instead of using .tmpl using real extensions needed for 2 and still work like templates

Planned next:

1. Add unit tests for all the above
2. Replace existing file by file generators to directory generators

templating still works with real extensions

[kb-commit]

this provides a very generic templator that we can use for any directory

I think this makes sense - but i don't think everywhere will be able to use it at-least in some of the backend pieces. So I don't think we could replace everything with this. Though the majority should be able to use this.

How would this work for bits where each file needs a bit of additional context like here https://github.com/commitdev/commit0/blob/f679a5cb7eedf23c3f08a612a65ba5b7f4fee9f2/generate/proto/generate.go#L69 ?

Also should this live in the util package?
