Bug in example 16_dynamic_data.html

Hey guys,

I came up with this bug by creating my own filter for the nodes, pretty hard to find: Issue: It is not possible to delete a node with the function nodes.remove(id) if the property smoothCurves is set to false. You can try with your example 16_dynamic_data.html. Just add the option and remove a node, then try to move the graph... it will get some kind of freezed, the console output say: Cannot set property 'damping' of undefined.

By the way: is there any better way to do filtering on the nodes. I thought of just deleting all node IDs which are matching against some pattern. Are there any functions for this?

Thanks!
