Special thanks: Dr. Dave Watson, who allowed us to base this package on the prodigious work he did in producing his "nngridr" package. There would be no Natgrid if it were not for Dr. Watson's package and his permission to include parts of his work here.
Also, thanks to Dick Valent who told the author of the existence of nngridr.
