- Move logic from CommandMapper to CommandHandler
- Create "ResultStatus" on FoundCommandResult to precisely return the error case
Naming and structure not final
- Reduce tight coupling by passing list of available commands as param to CommandHandler
- Split command processing method into several smaller ones
- Remove unfinished logic for unlimited command arguments (reason: was not implemented and not used, probably needs another way to handle it once the need for it arises)
- Create test for CommandHandler
- Create Initializer class that only initializes AuthMe commands
- Move remaining method to CommandHandler
- Deprecate constructors on CommandDescription in favor of the builder
- Various cleanups and comments
