                Deployment notes:
                
                properties file 
                  I need to copy this to the MF
                    -> the path to the input file
                       the input file name
                       the path to the output file
                       the output file name
                       the state being reported
                  
                I need the data on the MF
                   /u/jearl/data/us/us-500.csv
                   /u/jearl/data/us/us-50000.csv
                   /u/jearl/data/us/us-1000000.csv
                   
                   
                I need 3rd party jars on the MF
                  /u/jearl/jars/commons-csv-1.5.jar
                  /u/jearl/jars/log4j-1.15.jar
