/* Uses SystemInfo on Windows to get system configuration
   details. The data is stored in CSV format, which consists of
   two rows, one for the headers, one for the data. 
   ZUtils.buildMap() converts this into a map: headers->data

   SystemInfo details:
     * https://www.computerhope.com/systemin.htm
     * https://ss64.com/nt/systeminfo.html

    Usage:
      > compile WinSys.java
      > run WinSys
