Title: Add an API for enabling/disabling zoom interaction.

Let me know if you have other ideas on how to do this. It's difficult because once `d3.behavior.zoom` captures a mousewheel event, there's no getting it back.

I'd like to use this to make the karyogram on cycledash listen for mousewheel events only after it's been clicked.
