/**
* FeatureVisitor interface to allow for container optimised traversal.
* <p>
* 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.
* </p>
* 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.
