Export validateDragHandle

[philipstarkey]

I have a use case where I need to add additional functionality to handleDragstart and handleTouchstart, while still calling the base handlers. I can do this easily enough (thanks for exposing them in the config and exporting them from the base module!) but when using drag handles, I have no way of determining if the base handleDragstart/handleTouchstart function has returned immediately because it wasn't the drag handle that triggered the event, or because it's finished successfully.

While it seems possible that a fix for #43 might address this, another immediate solution to my issue would be to export validateDragHandle(). That would allow me to verify the event was triggered by the handle before calling my extra code. It doesn't look like validateDragHandle is any more internal than any of the other exports, so I'm guessing there isn't any barrier to doing this?

Great question. I can export this as well. I'll get back to you when I get the chance.
