    Keep historical data in an RRD db, update it at each run and generate graphs
    
    Three scripts compose the RRD integration:
    
    * bootstrap_rrd.py - generates the initial RRD from a set of summary files
    * graph_rrd.py - generates graphs from the RRD db
    * update_rrd.py - updates the RRD with one summary, to be used after each run
