simpler_model.ipynb : modified the time serie plot (moving average of 3 days), added RVE and MAE as metrics, created pandas data frame out of it and export them as tex tables, modify remku command to account for tex files

2 different models for the Penman approach : internally varying sruface resistance and constant one with stress factor at the front. Changing name file system

- new folder called scen1 with sub folders "naive_run" (= work until now, no calibration, default values by Feddes) and "calibration"
- changed Renku command file

investigating time dynamic of indicators (RMSE and Nash), implementing nt coeff in analysis_functions.py and updating renku command file for graph production

adding export graphs in script for renku, renku command file updated, updating resample size to 2000
