#628 - a feature has a geometry - a geometry doesn't have a feature - features are rendered, selected, moved, modified, etc - down in the renderer, expando properties on nodes are limited to _featureId, _style, and _options - this removes expandos that created circular references back through the map and to other dom elements - when the renderer is involved in selecting features, it returns a featureId (instead of a geometry or feature) and the layer is responsible for fetching the appropriate feature
