/**
* FeatureVisitor interface to allow for container optimised traversal.

* The iterator construct from the Collections api is well understood and loved, but breaks down
* for working with large GIS data volumes. By using a visitor we allow the implementor of a Feature
* Collection to make use of additional resources (such as multiple processors or tiled data)
* concurrently. This interface is most often used for calculations and data transformations and an
* implementations may intercept known visitors (such as "bounds" or reprojection) and engage an
* alternate work flow.
