Rename relations *usageZones* and *thermalZones*
Created by: JoachimBenner
In the CityGML standard as well as in the EnergyADE, most relation names are stated in singular. This has a good reason, because in the XML encoding the relation property either points to (via xlink:href) or imbeds exactly one related XML-element. Thus, the new relation thermalZones (_AbstractBuilding --> ThermalZone) must be instanciated once for every ThermalZone of the building, and the plural usage in the relation name is misleading and inconsistant with the rest of the data model. The same situation occurs with the relation usageZones (_AbstractBuilding --> UsageZone).
- Rename thermalZones --> thermalZone
- Rename usageZones --> usageZone
