Function.extractParams is deprecated.

Hello,

> I get this message from Atom's Deprecation Cop

Assigning custom properties to a marker when creating/copying it is
deprecated. Please, consider storing the custom properties you need in
some other object in your package, keyed by the marker's id property.
