The final goal is to move to Design by Contract paradigm.
For TPC detector this would be:

• libtpc should be library of interfaces and base invariant classes (API for tpc, located in /detectors/tpc/)
• libtpc then loads libraries with specific implementations, for example libtpcClusterHitFinder located in /detectors/tpc/clusterHitFinder
• the constraints on the implementations are the tests (which in fact are requirements written in computer language) implemented in Acceptance TDD.

This is modern approach to long term stability & continuous improvement in software engineering.
Perfectly suits for our scientific project.

!!!This is currently of highest priority!!!

• So far all tasks below are marked with this milestone.
• Separate into smaller milestones, estimate priority, size, scope.
• Then assign each task to its corresponding (newly created) milestone and close this one.

LOADER

• settings
• geometry

UPPER ABSTRACTION LAYER FOR SIMULATION

UPPER ABSTRACTION LAYER FOR RECONSTRUCTION

• reconstruction of simulated events
• reconstruction of real events

GEOMETRY

• Base class having invariants such as number of rows, sectors etc
• inherited classes describing multiple geometries, such as aligned

UNIFICATION OF BASIC OBJECTS CLASSES

• clusters
• hits
• digis

FAIRTASK INTERFACES

• TpcClusterHitFinder
