public interface MapFilterChain
Used to set up a filter chain for adding map elements to an area of the map at a given level.
Although this is based on servlet filters, there is a complication in
that we want to be able to split up an element, this lead to the
addElement(MapElement)
method which in effect creates a new chain
that is at the same stage as the current one and with the same final
destination.
