VariantSync Core Library

[pmbittner]

This is a long term issue.

Core functionalities of VariantSync that are independent from the IDE should be developed independently in a dedicated library.
Thus, the plan is to create a new java library (preferrably as a Maven project of archetype maven-archetype-quickstart in this repository) that can be included as a jar file.
In the later future, core library should hold unified data structures and functionality for

• Software Artefacts
• Variants / Clones
• Project Structure
• View Configuration (Colours for Traces?)
• Serialization of Feature Traces
• Pull-Requests / Cherry Picking / Synchronisation Broadcasting

So the next steps would be:

1. Setup the library project with package name de.variantsync.core.
2. Implement data structures: These will be planned with a special issue each.
3. Refactor the VariantSync Eclipse Plugin to use the library and its content.
