## Detailed Description

Computes the location of points relative to an areal Geometry, using a simple O(n) algorithm.

This algorithm is suitable for use in cases where only one or a few points will be tested against a given area.

The algorithm used is only guaranteed to return correct results for points which are not on the boundary of the Geometry.

Version:
  1.7
