Included the animalfeednutr sheet  based on demis sheet. Refers to issue #42 Animal nutrition sheet in the Cifos-Model EU remote repos

The FertNutr sheet was combined with the FRV sheet. The HumanNutrSheet was updated. A function was added to read cifos model data easily.

Continued with the grassland checks. Checked hyde documentation and adjusted the comparison accordingly. It still shows quite large deviations between our data fro grass and crop and the faostat land use data set. Gotta talk to hannah. Arable land looks better when comparing with fao. Also checked the FAOcode and realized that they differ from GAUL code. Be mindful!

visualization functions for comparing the deviation of our extracted area data with FAOSTAT and EUROSTAT is fiished and works (look for ggarrange function in script)

Also started to compare the area extracted (by Leandro and Me) with the EUROSTAT and FAOSTAT values.
Found a major bug: country_map seems to be not matching the country codes from the FAO sheet. @WJS: check again what is going wrong here!

finalized the grazing grassland approach where the prod_level is now selected based on the potential and the current grazing intensity. Current is based on EUROSTAT grazing intensity. While the maximum is based on the stocking rate with the highest yields  per zone.

Food supply, protein supply and imporrt export are adjusted to work with the bulk downloaded input file from FAOSTAT.

In model data script: worked on newly discussed Import export approach where we substrat the non food and stocks from the import to get more realistic results .In progress.
In grassland: the stocking rate approach is implemented where we have potential (highest) and realistic stocking rates expressed in LSU/ha (0-2)

Grassland (stocking density change not yet done) and  model data update (processing sheet update with JD)

Worked on the whole script, focus on integrating the food groups and created new baseline sheets for import export and food supply.

Name convention was used: for for forage products. in for procin. 1 for forage crops. 1-DM for grassy crops. Ollies data was used when no values in tcf fao document.

adding all the different csv and some selected excel files. Now the model data scrip can be run with the available data sets here.
