Remarks

ClosestFacilitySymbolizer allows you to create a new symbolizer for use with a closest facility layer and register it with the NASymbolizer category. If a symbolizer has a higher priority than the default symbolizer then it will be used in place of the default symbolizer. For example, the default facility symbol could be changed from a dot to a cross.
