migration lines with directions #11
Description
The generated KML graphs may get cluttered. Adding arrows to the end of line
segments may improve a little, representing lines as >>>>>>>>>>> may improve a
lot.
KML lines only allow a core and outer color:

Open Layers allows dashed and dotted lines:

eature/Vector-js.html#OpenLayers.Feature.Vector.OpenLayers.Feature.Vector.style
Still not what we need though dotted lines may result in more blending effects
than just transparency.
