- A lot has changed since 1.0
- The source link is simplified and has a corresponding measurement
class now
- Copied Bfield and utilties from acts examples
- Currently it only compiles. Need to check reconstruction.

It Builds with acts 4.1.0

- All charges (-1,0,1) are added to the candidates
- The initial vector points to the EM cluster, set with momentum equal
to the energy where we assume a massless particle
- Added new seeding algorithm which uses Ecal clusters and Vertex
tracker hits.

- Fixed algos which are affected by changes in eicd.

- The system of units is still a bit rocky.
- This might have something todo with the dd4pod output action. Need to
double check.
- Track finder works too well if it is seeded with initial track
parameters that include the exact thrown momentum.

This goes with the update to eicd removing cellID0 and cellID1 from all
data types.

- 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.
