* Finds the most likely Location of a point relative to

* the polygonal components of a geometry, using a tolerance value.
|
|
*
|
|
* If a point is not clearly in the Interior or Exterior,
|
|
* it is considered to be on the Boundary.
|
|
* In other words, if the point is within the tolerance of the Boundary,
|
|
* it is considered to be on the Boundary; otherwise,
