CREATING A REFERENCE PRICE FILE

  The goal is to create a file that gives a reference price for BTC in USD
  for the Western exchanges.  
  
  There is no exchange whose operating life covers the entire life of bitcoin. To get the complete
  price history, we must merge data from several exchanges, specified in the index file
  
    rundate="2019-10-28" # Nominal date of experiment.
    dmin="2010-06-20"    # Min date for plot.
    dmax="2019-10-26"    # Max date for plot.
    make_and_plot_ref_price.sh "${rundate}" "${dmin}" "${dmax}"

  Recomputed on 2015-05-25 to blend hi/lo instead of taking union.

  Recomputed on 2016-10-31 to add data between 2015-05-26 and 2016-10-30.

  Recomputed on 2019-10-28 to add data up to 2019-10-26.
  
    cp out/2016-10-31-refprice-01d.txt ../00-DATA/series/fix/2010-07-17--2019-10-26-PREF-USD-01d.txt
