Detailed Description
Geometry classes support the concept of applying a coordinate filter to every coordinate in the Geometry.
A coordinate filter can either record information about each coordinate or change the coordinate in some way. Coordinate filters implement the interface CoordinateFilter. (CoordinateFilter is an example of the Gang-of-Four Visitor pattern). Coordinate filters can be used to implement such things as coordinate transformations, centroid and envelope computation, and many other functions.
A CoordinateFilter should be able to process a CoordinateXY object and can optionally provide specialized implementations for higher-dimensionality Coordinates. If the behavior can be templated on coordinate type, then a filter may inherit from CoordinateInspector or CoordinateMutator to generate these implementations from a template.
