Split into Core and GUI repositories

[nebw]

The biotracker repository should be split into two parts for the following reasons:

• Multiple applications in the Lab depend on some parts of the BioTracker, but not on the GUI component.
• Seperating the two parts would lead to a cleaner codebase and make testing (of the core components) easier
• The TrackingAlgorithms should only (explicitly) depend on the core components
• Integration with cpm would be easier
