Wow, it does work. Thanks a ton. And, it is supremely complicated. I still
don't get why a styleMap is being assigned to the layer, only to reassign it to
the point on the layer. And, what is the point of putting "bind values" in the
template, but then use functions to returns values for those values. Might be
helpful to understand the chain of commands in OL as each point's definition is
encountered and it is rendered on the layer.
Now, I have figure out why `layer.events.on({"featureadded": function(event)
{}});` is not working.
