//////////////////////////////
// Some light documentation //
//////////////////////////////

// Indices are as follows
// e == entries in trees
// i == kinematic variables: pt, phi, eta
// j == reco track collections: seed, build, fit
// k == pt cuts
// l == rates: eff, dupl rate, ineff (efftree), eff, dupl rate, fake rate (print)
// m == eta regions: brl, trans, enc (efftree)
// n == track quality plots: nHits, fracHits, track score (frtree and print)
// o == matched reco collections: all reco, fake, all match, best match (frtree), all reco, fake, and best match (print)
// p == diff of kinematic variables: dnhits, dinvpt, deta, dphi (frtree)
// q == n directories in frtree

// Variable name scheme
// *_var(s)_* == kinematic variables (index i)
// *_trk(s)_* == reco track collections (index j)
// *_ref* == variable associated to reference tracks (CMSSW or Sim)
// kinematic variable name comes before trk name to maintain consistency with branch names
// mask name also obeys this rule: which type of mask, then which reco track collection for association
// in case of "_ref_trk", this means this a reference track variable associated to a given reco track collection

// f* == data member
// s at the start == "string" version of the variable
// h at the start == a different string version
