Added calculation of the "Umhuellende" to calculation of "W fuer ungleichwertige Abfluesse". This is done by figuring out the WST columns that imfold the data and then do simple "gleichwertige" calculations from the start of the interval. This is too much because only the Qs are needed for the "Umhuellende".
