Interface

• $gun(soul) Returns a proxy object that contains the entire tree of the node (with open()), including _ properties for metadata. Will update the component on every update of the data. TODO currently updates the entire tree. TODO currently there is no way to unsubscribe
• $setOf(node object, property name) Returns an array with the values in the node TODO cannot get keys, maybe rename to $entries and return key value pairs?
• $addToSet(node object, property name, value) Does gun(node soul).get(property name).set(value).
