/** This routine is called from the filter program (or can be called
    directly with the correct arguments) and summarizes the users filterlog
    file.  To be honest, there are two sorts of summaries that are
    available - either the '.filterlog' file can be output (filter -S) 
    or a summary by rule and times acted upon can be output (filter -s).
    Either way, this program will delete the two associated files each
    time ($HOME/.filterlog and $HOME/.filtersum) *if* the -c option is
    used to the program (e.g. clear_logs is set to TRUE).
