public class MexicanHatFunction
Multi-dimensional Mexican Hat, or Ricker wavelet, function. It is usually only referred to as the "Mexican hat" in the Americas, due to cultural association with the "sombrero". In technical nomenclature this function is known as the Ricker wavelet, where it is frequently employed to model seismic data. http://en.wikipedia.org/wiki/Mexican_Hat_Function
