I added the functions fit.gaussian and fit.spherical similiar to fit.exponential.

Because of the lack of a persp() plot function in R, I changed calls to it (in
 fit.trend() ) to contour().

The help pages stem from the original HTML help at

I added a dataset "maas" which originally belongs to "gstat", a geostatistics 
package from E.J Pebesma (E.J.Pebesma@frw.uva.nl) available at

http://www.frw.uva.nl/~pebesma/gstat/

with measurements of zinc as a groundwater quality variable. Details can be 
found at the URL above, e.g. a GIF-picture (zn_map.gif) with coordinates (it is 
also included here). The dataset "maas.bank" contains coordinates of the maas.bank, shown in zn_map.gif.
