> This came up on the listserv. Someone wanted a way to turn (start,end) ranges 
> like {(1,3),(2,2),(3,4)} into a timeseries with the number of ranges which 
> include the given time ie {(1,1),(2,2),(3,2),(4,1)} with an optional lag 
> parameter. This patch is that. I included tests. Maybe there is a better 
> name, or this should be in a different package?
