- Null check on the language translator to prevent null pointers in the
console, instead it returns "NULL POINTER EXCEPTION" now. Might want to
handle this on a different approach, but it's the best for debugging now
because it shows up in the interface clearly where the errors are being
thrown (Dependencies were having null as type).
- Other icon for external systems.
- External Systems are now declared as 'library' when pulling in the
AnalysedModuleDTO's when calling getAllRootModules().
- AnalyseUIController no longer combines the external systems with the
analysed modules. This now happens in the AnalyseDomainServiceImpl
class.
