Use GeoSPARQL to type spatial relationships

[jabhay]

The following relationships between entities were identified and encoded into the ontology:

1. Addresses are within Localities (hasLocality)
2. Addresses touch Street Localities (hasStreet)
3. Street Localities are within Localities (hasLocality)
4. Localities link to GeoNames states (hasState)
5. Localities touch other Localities (hasNeighour)

However, they are not typed and could be using geo:sfWithin where the item is within another item and geo:sfTouches where they touch.
