Detailed Description

Base class to build tracker families.

Any tracking algorithm must inherit from GammaTracker to be used in the GammaWare.
Once a new tracker is loaded (see TrackerLoader.C), it must be allocated by using the static method GetTracker.
Because GammaTracker defines an general interface, it is kept as simple as possible. Inputs and outputs are just buffers of doubles. Inputs are energies and positions of the different impacts in the detector (with their associated errors). Outputs are the reconstructed energies, the emission angles (theta1, phi1) ands the direction of the second impact (theta2, phi2) for polarisation measurements.
Different tracking may work with different unit system. It can be checked/modified through the DistFactor methods. Once an event has been initialised (see SetEvent methods), the tracking is called with DoTracking(). The output buffers contain then the tracked gamma-rays.
