- (Object) ListSumCutOff(sizes, max_cutoff)

Sum up all positive list items, but cut off individual items at a maximum value. Negative return values indicate overflow of any individual item at "max_cutoff". In this case, the absolute value of the return value is "max_cutoff" * number of overflows. (e.g. >2hour + >2hours + 1:13:20 => >4hours
