1. Adjust conf/epic-import-subject-mrns.properties so that
    encryption properties are the same as those in the file, scheduler.xml,
    from the configuration folder of your Scheduler's tomcat

2. Then, to run the import-subject-mrns, you need a csv file with the data to
     process. Do not include a row with column headers, but just the data.
     Desired columns in this csv might be in any order, or intermixed
     with other columns, so you need to give zero-based offsets for the columns
     containing

        subject-id
        mrn
        site
        status
        puid

     E.g., if the path to your csv is /tmp/myCsv.csv, and if the csv simply has the
     above colummns, in that order, then you would invoke the program as below:

     <program> /tmp/myCsv.csv 0 1 2 3 4

     For each row, the program will look for subjects that match the ID and mrn.
     For those subjects, site, status and puid will be updated

   Choose either a or b:

     a. UNIX

     chmod +x importMrnUpdates.sh.sh
     ./importSubjectMrns.sh  <path-to-csv> <idIndex(zero-based)> <mrnIndex> <siteIndex> <statusIndex> <puidIndex>

     b. Windows

     .importSubjectMrns.cmd  <path-to-csv> <idIndex(zero-based)> <mrnIndex> <siteIndex> <statusIndex> <puidIndex>
