Exception-handling #3
Description
Implement exception-handling
We want to have a rock-solid exception-handling which makes debugging usage of the library easy and straight forward.
- Add our own exception-type and -handling-tools.
- Add three stages of debug-output: Silent, normal and verbose
- Make all parts of the library (at least the ones we have already) throw informative exceptions
- Unify exception output
- Have a first look if we have places where we want and can give no-exception promises
