    kcollect - Implement gnuplot output feature
    
    * Implement the gunplot output feature.  This feature currently
      hard-selects a set of fields (fields cannot be specified).
    
      Generates two graphs.  The first collects memory statistics
      and machine load.  The second collects cpu utilization and
      fault, syscall, and nlookup (file path resolution) rate.
    
    * In gnuplot output mode, -f will cause the entire dataset to be
      regenerated every 60 seconds (I don't see any way to avoid this
      to update an existing gnuplot window).
    
    * Finish implementing -o fields
