basemap, drawing a greatcircle passing the map borders

I think basemap requires numarray, presumably because of it's
dependence on nd_image, so if I'm not mistaken you example should be
rewritten to use numarray versions of the modules above. Eg,

  import numarray as Num
  import as MA

and so on...
