Added some function for SoilProfile1D helping Esther to fix this issue. Also made some other improvements and remarks (see #Bka near the Todo zant_xml). Esther has to review and delete these comments and also has to add data to her test as this is failing due to insufficient data. The data to be handled must be much more complete in order to have any chance of success.
