…arzeion et.al., 2012, including an altered calibration method. The `test_ben.py` file contains the corresponding unit tests.

 - Deleting the OGGM tests from the `test_ben.py` file

- Test for the routine computing the minimal and maximal glacier surface elevation
- Tests for the routines computing the mass balance relevant climate information
- Added `ben_params` as basename in the config file
- Minor changes such as typos and similar

- Test the monthly specific mass balance against the corresponding annual mb
- Test the annual mass balance against the 'manually' computed mass balance
- Add a comparison with the reference mass balance measurements to the spec mb test

- Added area-volume and area-lenght scaling parameters to `params.cfg`
- First steps on what will become the `BenModel` class

- Corrected typo in the `cfg.py`
- `step()` function of dynamic model
- `run_until()` function of dynamic model
Note: I'm well aware that the model does not work properly yet. Qualitative tests on Hintereisferner show not observed area/volume/length changes...

- Changed the name to VAScaling
- Solved problems with scaling constants
- Solved problem with time scales

- Testing the length, area and volume output against the OGGM

… mean of the repective time series.
