The usage of std::binary_function is really old legacy to define the functions
used in STL algorithms like std::sort. std::binary_function was deprecated with
C++11 and removed from C++ with C++17. Obviously it is still supported by some
compilers since compilation errors only occured with newer Apple clang versions.

Switch to the modern implementation using lambdas in the STL algorithms.
This also increase code readability since the code is located at the same place
where it is used.

The change was confirmed to not introduce changes in the output by comparing
the produced TTrees before and after the commit in all produced ROOT files.

cbm::algo::ca::TrackParamBase (and derivatives) are moved to the KfCore library (now, cbm::algo::kf::TrackParamBase)

Additionally, dependiencies are cleaned-up

There were rich ring finders in the L1 code base which were compiled and linked
into libL1. With the change in the build system this results in a circular
dependency between the L1 and CbmRichReco libraries which was resolved by
removing the classes from compilation.
With this commit the classes are moved from the L1 code base into the rich
reconstruction code base.

In case of two institutes in the copyright statement add both cities.
Add commiter if missing.

Unify user names in the license header authors list.
Remove duplicate users in the authors list.
Cleanupo of some other inor issues.

Decision to not use doxygen for licence headers. Removes doxygen formatting and file tag.

Pulls some author and date information from previous headers, adds this to information from the svn and git repositories.
Inlude the standard copyright header to approximately 2000 files with institute of original committer as copyright holder.
Contributing authors from previous declaration and repository records.

* Add CbmEvent to RICH track extrapolation procedure.
* Add CbmEvent to the RICH track projection procedure.
* Add CbmEvent to ring reconstruction procedure.
* Add CbmEvent to ring fitting procedure.
* Add CbmEvent to ring-track matching procedure.
* Update run macros.
* Fix compilation error, include Logger.h
* Fix problem when CbmEvent::GetNofData return -1.
* Change some LOG outputs to debug mode.

The class FairLogger is  meanwhile only a wrapper around the Logger class,
so use the Logger directly. This also helps to reduce many warnings when
using the Eclipse IDE.

Apply code formatting to all source/header files and root macros.

The old SVN repository will still be available for read access.
