Detailed Description

ConfigBlock for the jet reclustering algorithm:
run FastJet with small-R jets as input. The output
is a new container containing the reclustered jets.
The default output variables are the RC jet kinematics
as well as a vector of indices pointing to the
small-R jets that formed the RC jets.
---- to be updated with substructure variables!
