Draft: Main package architecture

Description; Added the main architecture for the main packages. This merge is mainly needed for the POC which is and will be integrated this week.

To Check; IMI file - can I safely delete this? Sample Data - Happy with the sample data? Unit and integration tests not made because this is simply the start of the integrated POC which all other field research POC's need to abide by. Besides for the Compiler. Which is its own product.

Important Commits; Added; Implemented Hexagon pattern using 3 packages, Domain, Driver and Infrastructure to develop the program more clean; Added; Hibernate Session factory usage to more easily work with Hibernate Sessions; Fixed; Pom fix so that tests run.

Closes ASDCBA-219
