[R-sig-Geo] extract lat-long pairs - slot "coords"

[Brandon Payne]

I was able to get the coords to print to the R-console.  Still need to
read the docs on the Polygon class to access them.
(It's not  Golan$coords   )

```{pseudo}
# download
"http://biogeo.ucdavis.edu/data/diva/adm/ISR_adm.zip",
# extract
unzip *.zip
```

```{r}
states <- readOGR("../includes/ISR_adm/ISR_adm1.shp", "ISR_adm1")
Golan <- subset(states, NAME_1 == "Golan")
## check
## based on http://stackoverflow.com/questions/25985395/how-to-subset-a-shapefile
dim(states)
dim(Golan) 
Golan

```
