public class NewZealandMapGrid extends MapProjection
This is an implementation of algorithm published by Land Information New Zealand. The algorithm is documented here.
Implementation note
This class make extensive use of Complex type which may be costly unless the compiler can
inline on the stack. We assume that Jave 6 and above can do this optimization.
