mapping tables for area domain and sub population categories
Add tables that will map composed categories of area domains (c_area_domain_category) and subpopulations (c_sub_population_category) into the atomic categories.
This change is needed in order to be able to configure ratio estimates in a safe and efficient way, particularly when it comes to the determination of meaningfull combinations of subpopulation categories between the nominator and denominator and result additivity checks (categorization additivity).
These mappings will also be used to guide users looking up NFI estimates of their interest on the NFI www.
