Hello

In short:

  - Ecal - Track matching works good for MC
  - Track matching + charge sign cut were added to Di-lepton
    analysis and looks promissing on PYTHIA events
  - Codes are in Daniel's GitHub "fwd-tracking" branch
     https://github.com/jdbrice/star-sw-1/tree/fwd-tracking
  - Updated README

https://github.com/jdbrice/star-sw-1/blob/fwd-tracking/StRoot/StFwdTrackMaker/macro/sim/README_AKIO

To do:

  - Adjust some cuts (dR < 10cm seems too loose, at lease for Ecal
    and  MC, Ecal cluster energy cut set too low to include MIP, etc)
  - Add more statistic for DYBG MC
  - Run over day 74 FastOffline data with Xilin's gaincorr

More details:

 With enabling vertex & FST in tracking, and a bug fixed on my part (a 
typo which killed matching at south side), I am getting reasonable 
FcsEcal-Track matching for single particle MC (mu+, e-, pi+), as well as 
PYTHIA DY,Jpsi and DYBG (MB with DY filter). Note that Daniel is working 
on track projection to Hcal, so do't look at Hcal plots just yet):

I hope histogram titles and axis labels(for 2d plots) make
them self explanatory...

Here are plots from DiLepton analysis code on PYTHIA events:
