We also need to enable dataset in the code. I think we might change the code to get all datasets we have in the directory. With the use of extra metadata property in yaml file like show or active we can always disable any of them. value_column could be also moved to yaml file. parse_value function, hmm, that one could stay or also be in yaml file as text that will be executed dynamically.

This is till WIP, right @edwardpmorris? until we get the data calculated in %?

this is ready ☝️ As Tomek suggested, we now get all the datasets from map_data folder and parse them if they have set active: true in the yaml metadata files.
