- [x] Import bootstrap functionality from lmvc as utility "module"
- [x] Integrate bootstrapping logic to be compliant with lmvc-modules
- [x] Bump coverage for bootstrap util to 100%
- [x] Test the StringUtils to with 100% coverage

Feel free to add comments, wishes or observations in other log libraries. It would be kinda good to get a decent set of the good parts in here and leave the complexity of bad parts out.
