Add functionality to focus camera on a graph node from IFC

[DiegoVinasco]

This functionality already exists (currently in the GeoDataDays demo soon to be integrated) for CityGML.

However, the structure of identifiers of entities (features) in IFC graphs produced by the IFCtoOWL tool is slightly different from those produced by UD-Graph and GML data.

Thus IFC specific queries or functionality need to be implemented capture these IDs to retrieve the correct cityobject from the batch table.
