    - add Calc.cum to aggregate Measurements.
    
    - add ΣMeasurement type to represent result of this. It is very similar
      to Measurement, but every field comes accompanied with information
      about how much time there was no data for that field. In other words
      it is not all or nothing for NA in the result. For example a field
      might be present 90% of the time and NA only 10% of the time. We want to
      preserver knowledge about that 90% of valid values in the result. And we
      also want to know how much time there was no data.
    
    - amend kpidemo.py and kpidemo.ipynb to demonstrate this.
