rem "For" loops through the specified directory taking all the files that match 
rem    the spec and doing the commands following "for."
rem
rem The for loop does these things:
rem   -- runs explode.exe over every matching file
rem   -- saves the output to a directory of year\qtr\filename.dat
rem
rem Input Parameters:
rem %1 - 4 digit year
rem %2 - 1 digit quarter
rem %3 - 2 digit year
