So, I changed a lot of code to reduce boilerplate on models in the future. Currently we do not have a lot of models, but this can increase quite rapdly. There's a second TreeModel in the works, the Yearly Statistics, this patch will save around 250 LOC for this new model, and more and more models will give us a greater saving. Iwll do that for the table models in the future too - I did the tree models now because they are the most complex case and I didn't wanted to create a second tree model without this.
