More control over bounds

[tra]

I have some situations where I'd like only a subset of my markers to contribute to the bounds when the map is displayed. For example, multiple locations of a franchise, but I'd like to zoom to the closest locations and have the further locations on the map for when the user zooms out. I can see a couple ways to solve this. First, you could give me a callback or some way of setting the bounds manually. Second, you could have a way of marking locations as to whether or not they contribute to the bounding calculation. I think I would prefer the latter. What do you think?

Here's my solution to this issue.
