* A TopologyLocation is the labelling of a
* GraphComponent's topological relationship to a single Geometry.
*
* If the parent component is an area edge, each side and the edge itself
* have a topological location. These locations are named
*
* - ON: on the edge
* - LEFT: left-hand side of the edge
* - RIGHT: right-hand side
*
* If the parent component is a line edge or node, there is a single
* topological relationship attribute, ON.
*
* The possible values of a topological location are
* {Location::UNDEF, Location::EXTERIOR, Location::BOUNDARY, Location::INTERIOR}
*
* The labelling is stored in an array location[j] where
* where j has the values ON, LEFT, RIGHT
