Helper function under UCHelpers namespace. This will soon contain a helper function which takes in an R=N jet, uses the AntiKt4LCTopoJets, creates a deep copy that matches up the AntiKt4 jets to the AntiKtR jet using dR<=R and return that for further reiterations, such as counting the number of btags, or top tags, etc. [I have a function that ^Cunts the number of btags given an xAOD::JetContainer*]
