IPolycurve3D.Weed3D Method

Generalizes using a small tolerance based upon either the system units of the geometry's spatial reference, or the geometry's bounding box.

Weed generalizes each part of a Polycurve into a generalized collection of z aware Line segments.  Weed performs a Douglas-Poiker Generalization algorithm, extended to operate in 3D space, with a specified multiple of the internal tolerance given as input.  For Line segments, the Generalized output is a subset of the original input vertices.  For non-Linear segments, the Generalized output contains points along all parts of the curve, not necessarily only the vertices.
