[R] spatial/ patches and gaps/ SADIE

[Ben Bolker]

   I don't think anyone has implemented SADIE in R.
It's not very widely used outside of ecology, as far
as I know ...  (just checked Web of Science, there
are 70 hits for "spatial and SADIE", and they're all
ecology/entomology/phytopathology).

  I don't know what the licensing is like for
SADIE, but I wonder if it would be worth writing
an R interface ...
