WEBCERT-592: Ytterligare refaktorering av diagnoskodvalideringen.
Added code skeleton.

Generated through maven archetype for version 1.2 and modified to fit 1.3. Still
contains discrepancies that needs to be addressed.
Starting work on parsing MIM for SLU.
Restructuring code to look like the other modules.
Adding external model. Not finalized.

There are some extreme inefficiencies in the model as in the MIM. Will implement
if required.
Transport to external converter done.
Start of ext->transport and better nullhandling.
Additional and cleaner functionality in converter.
Completing exernal -> transport.
Adding missing Vardgivare (not present in MIM).
Fixed tests and created first resources for it.

Starting to add files with valid configurations that should be able to be
converted by the convertors.

Valid-minimal might be too small.
Removing old debug code.

Was used to see what was generated by converter.
Adding internal model.
Adding first part of converter external->internal.
Code cleanup in transport->external.

Code that was obsolete because of util function in IsoTypeConverter.
Renamed field to match model.
First external->internal complete.

Missing code system which Mattias will construct.
Adding observationssamband.
