* Compute the overall ON location for the list of EdgeStubs.
*
* (This is essentially equivalent to computing the self-overlay of
* a single Geometry)
*
* edgeStubs can be either on the boundary (eg Polygon edge)
* OR in the interior (e.g. segment of a LineString)
* of their parent Geometry.
*
* In addition, GeometryCollections use a algorithm::BoundaryNodeRule
* to determine whether a segment is on the boundary or not.
*
* Finally, in GeometryCollections it can occur that an edge
* is both
* on the boundary and in the interior (e.g. a LineString segment
* lying on
* top of a Polygon edge.) In this case the Boundary is
* given precendence.
*
* These observations result in the following rules for computing
* the ON location:
* - if there are an odd number of Bdy edges, the attribute is Bdy
* - if there are an even number >= 2 of Bdy edges, the attribute
* is Int
* - if there are any Int edges, the attribute is Int
* - otherwise, the attribute is NULL.
