This commit adds the necessary logic to do hole search to the
GlobalChi2Fitter. The implementation is very close in output to the
InDetTrackHoleSearch, and may even improve on its quality slightly. The
hole search, if enabled, adds some CPU time to the fitting process but
this is negated by reduced CPU time later on in the algorithm chain. The
hole search data is carried out of the fitter through a track summary
object attached to the track. This functionality is disabled by default
to preserve exact bit-to-bit equality of the output, but can be enabled
using the DoHoleSearch flag. The rest of Athena should by now be
configured to accept this and work around it without performing
unnecessary additional hole searches.

This commit adds a boolean flag to our existing propagation helper used
in the global \chi^2 fitter that enables it to also do an extrapolation,
gathering not only the position where the propagation lands but also a
set of surfaces crossed in between.

In order to do our hole search, we will need to do a slightly modified
version of the stepwise extrapolation provided by the extrapolator
interface. This commit adds a helper method to the TrkGlobalChi2Fitter
that provides this functionality.

In the future, we will want to store hole search information in the
GlobalChi2Fitter's internal representation of a track state. This commit
adds the necessary data members as well as getters and setters to make
that possible.

There is really no reason for this getter method to not be const. The
returned pointer is to a const value, and the non-const qualification
makes it impossible to use this extremely useful getter in non-const
contexts.

Previously, this class had no getter to access the track states stored
within. That's a little bit weird, because it is something we access a
lot. This commit adds that getter.

For future changes, we will need to access header files defined in the
InDetReadoutGeometry to implement hole search. This commit adds the
dependency on that package to the CMake file of the TrkGlobalChi2Fitter.

This commit adds a configurable parameter to the TrkGlobalChi2Fitter
which enables it to do a hole search and export that information via a
track summary. It's disabled by default, and it doesn't actually do
anything yet. Actual hole search logic will be added later.

Xiaozhong Huang authored 4 years ago and Adam Edward Barton committed 4 years ago

When PanTau fails, the p4 will at the default value, i.e. -1111. As
it has bad consequence when retrieving the p4, we now set the default
four momentum at TauEtaCalib.
