Typo
Fix #42 -- provide packaging scripts and fix $PIDFILE variable naming
avoid exceptions by checking series early. fix #37

in normalize()
TypeError('reduce() of empty sequence with no initial value',)

also there are a few other cases where we rely on seriesLists being
valid, populated lists.

Bruno suggested that seriesList and seriesLists may evaluate to False.
I have seen that sometimes seriesLists is ([],)
So if we hit those cases, return early.
