Changed how manual water lvl measures are inputed.
(1) Changed the format of “validation_niveau.xls” to “waterlvl_manual_measurements.csv” which is now a tab separated text file to be more consistent with the rest of WHAT input files.
(2) Changed the format of the information contained in “waterlvl_obs.csv” to keep only the needed info.
(3) Changed the references of the water level to be mbgs, positive downward.
(5) “waterlvl_manual_measurements.csv” is now loaded from the selected project directory instead of the global folder of WHAT.
(9) Moved the function “load_water_level_measurements” in class “WaterlvlData” as “load_waterlvl_measures”. Made the changes to “generate_hydrograph” and “WHAT.py” accordingly. Water level measurements info is now loaded in WHAT.py when a Water Level Data file is selected in the method “select_waterlvl_file(self)”
(10) Code cleaning and commenting.
