Class GeometryNoder

Nodes the linework in a list of Geometrys using Snap-Rounding to a given PrecisionModel.

The input coordinates do not need to be rounded to the precision model. All output coordinates are rounded to the precision model.

This class does not dissolve the output linework, so there may be duplicate linestrings in the output. Subsequent processing (e.g. polygonization) may require the linework to be unique. Using UnaryUnion is one way to do this (although this is an inefficient approach).
