Requirement: Core shall provide generic support for expressing changes in the simulation model
This is one step towards realizing the above requirements. In this PR, the classes that define the event and data for relevant model changes are moved from the SPD to the core. This way, we break the dependency from other extensions to SPD concerning model changes. However, the current structure has to be revised to fulfill the requirements above.
