	LundPlane FastJet contrib
	------------------------------------------------------------------------

	The LundPlane FastJet contrib provides tools necessary to construct
	the Lund Plane of a jet.

	It is based on arXiv:1807.04758 by Frederic Dreyer, Gavin Salam, and
	Gregory Soyez.

	It provides the following C++ classes:

	- LundDeclustering
	Contains the declustering variables associated with a node on
	the Lund plane.

	- LundGenerator
	A tool to generate a vector of LundDeclustering for a given jet
	corresponding to its primary Lund plane.

	- LundWithSecondary
	A tool to generate primary, and secondary, lund planes of a jet
	according to the definition given as input.

	- SecondaryLund, SecondaryLund_{mMDT\|dotmMDT\|Mass}
	Provides a definition for the leading emission.

	There are two C++ examples which can be compiled with

	> make example example_secondary

	The example program can be run using
	> ./example < ../data/single-event.dat

	and will output the primary lund plane declusterings as well as
	generating a jets.json file, which can be read by a python script:

	> python3 ./example.py

	Some python classes to assist with reading and processing the json file
	are provided in the read_lund_json.py module.

	The example_secondary program outputs both the primary and secondary
	Lund plane declusterings to screen, and can be run with:

	> ./example_secondary < ../data/single-event.dat
