proj4 work
proj4 mapLines() works
proj4 detected better

proj4 maybe fix mapImage
Merge branch 'develop' into proj4
proj4: improve memory method
proj4: mapLocator() works

proj4: mapLongitudeLatitudeXY() works
proj4 docs
proj4: different invocation
proj4
proj4: stere error fixed

proj4: broken (transit checkin)

Not getting good inverse on test:

library(oce)
source('map.R')
cs <- list(longitude=-64.49657,latitude=45.33462)
xy <- lonlat2xy(cs, projection="mercator")
xy2lonlat(xy)
lonlat2xy() and xy2lonlat() pass (one) test
