Sap Flow development

[mmaelicke]

This is the missing stuff from #20:

General function layout for sap flow tools.
I provided the main functions in sap_flow.py and utility and correction functions in util.py.

ToDo

• add descriptions to all docstrings
• check the parameters for data type and possible default values
• add data example, write unittests
• implement the code
