determineBoundary static method
This method implements the Boundary Determination Rule
for determining whether
a component (node or edge) that appears multiple times in elements
of a MultiGeometry is in the boundary or the interior of the Geometry
The SFS uses the "Mod-2 Rule", which this function implements
An alternative (and possibly more intuitive) rule would be
the "At Most One Rule":
isInBoundary = (componentCount == 1)
