#  script to view the output of a previously created run.xml file
#  rerunning the simulation with new data is outside of the scope
#  of this script. it is currently only for viewing the output
#  of a previously created run.xml file.
#  
#
#  RUN AS FOLLOWS:
#    rerun [-h | -d driver_path] <run.xml-file>
#
#      -h | --help                  - print the help menu
#      -d | --driver driver_path    - specify the path to the driver 
#                                     program. You will need to specify
#                                     the path if the driver program is
#                                     not in your PATH environment 
#                                     variable.
#
#      <run.xml-file> - the run.xml file you containing an output 
#                       section you would like to re-generate.
