* `type` : `subflow`
* `id`
* `name`
* `in` - the id of the internal node that provides the flow's input port.
* `out` - an array identifying the internal nodes and their output ports that are mapped to the flows outputs. Elements are objects of the form: `{id:ID, port:PORT}`.
A node that is part of a subflow has their `z` property set to the `id` of the subflow.
An instance of a subflow has the following properties:
* `type` : `subflow` ... ?
* `type` : `subflow:ID`
* `id`
* something to identify mode... if we have modes.
It inherits the `name` of the parent subflow.
**Questions:**
* how does an instance node identify its parent?
* type=subflow:'parent-id'
* type=something other than subflow and parent=<parent-id>
* `singleton` : true/false
* `name` - if singleton, inherits from parent subflow
