- Some were making the same casting mistake. That should be fixed now.
See !62 for
details.
- Missing headers.
- SOIPIXTrackerDigi same as UFSDTrackerDigi except with poor time
resolution

Because of bad c-style cast the block energies being truncated at 1 keV, they were being
truncated at 1 GeV!!!

This was updated using a nice round function with explicit return type: https://en.cppreference.com/w/cpp/numeric/math/round

- moved `containers` to `.containers`
- cleaned up some of the old singularity files in `.gitlabci`
- removed rootfile.

- Using same rules for pushing new docker image.
- Running physics and reconstruction

- Note that the usage of Gaudi's eV probably mirrors the G4/CHLEP units so it
works fine.
- The internal juggler units are (GeV, mm, ns, rad)

- Note that units do not need to be used internally. Only when values
are needed outside of gaudi.
- The default units are (GeV, mm, ns, rad)
- Fixed units in algorithms

	modified:   VERSION

- Hits must fall within this radius to seed a track.

- TrackingHitsSourceLinker takes multiple TrackerHitCollections
- Creates the source link for all hits (= tracker hit + surface object )

- 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.

- simple clustering algorithm returns one cluster.
- uses 3D hits

- added missing algo: EMCalorimeterDigi
- Cleaned up ci

- 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.

- I guess this is a bug in PodioInput/PodioOutput.
-  new file:   tests/options/col_copier.py
- Added class template InputCopier
- Split up CI for docker build into "build" and "push" stages.
