Allow user to define tooltip options for station markers

Not sure I understand how this would work. It looks like the tooltipoptions is passed into drawStationLayer(), but when that method is called from within draw() it is not passed as an arg? So I think this, as coded, can never do anything?

Am I misunderstanding something?

I do not call draw after the initial setup. I use drawStationLayer and drawQuakeLayer to update individual layers. And the tooltip styling works.

That seems dangerous as you can't be sure that some later event, like a resize, won't call redraw() in the superclass, which then calls draw() on the map, and draw() doesn't pass any args to drawStationLayer, effectively deleting the tooltips.
