- Added two random variables: the stochastic term (a), and constant term
(b)

- CMakeLists.txt
- JugReco/SourceLinks.h
- JugReco/src/components/ParticlesFromTrackFit.cpp
- JugReco/src/components/TrackFindingAlgorithm.cpp
- JugReco/src/components/TrackParamTruthInit.cpp

- Following the examples, the track finder is working with the
 hytop_test repo. There is still a lot of work to do but it is progress.
- Added source linker algorithm which uses just the reconstructed hits.
- Added track parameter initialization based on mc truth. This should be
replaced with proper seeding.
- Added TrackFindingAlgorithm following acts examples. This code is in a
single file and takes a long time to compile. This can be reduced with
some fwd declarations and headers.
