Navigation Data

About

The nav data seems to be built using the INavRelevantInterface interface with GetNavigationData. For example UPrimitiveComponent implements it, as well as the parent of UNavModifierComponent, UNavRelevantComponent.

DoCustomNavigableGeometryExport is called before GetNavigationData.
