Dbus Object List

Dbus Object List is a helper library for a common Dbus pattern- properties which are (perhaps changing) object path lists.

Provides:

• Dbus Object List retrieves the initial list, and subscribes to New and Removed signals for the list to keep itself updated.
• When provided a Dbus interface string and bus generating-function, it builds objects for the object paths. Instead of being a list of paths, it serves as a mapping object path => Promise.
• When provided a (bound) emit function, it emits events for add and remove, using the name, and providing value, objectPath event arguments.
