 /*
    Todo:
      Add reading of DDL files so we can futher explode DMP packets
      For some of the Set/Get properties where we have a range of data
      it would be better to show the block of data rather and
      address-data pair on each line...

      Build CID to "Name" table from file so we can display real names
      rather than CIDs
