/** A Node to represent input/output Ports on a Patch.
*
* This node acts as both a Node and a Port (it is the only Node type that
* returns non-null for as_port()). The node is a normal Node in a Patch,
* the Port is a Port on that Patch (port->parent == node->parent).
*
* This class handles all DriverPort functionality as well (if this Node
* is on a top level Patch).
*
* Both input and output nodes are handled in this class.
*
* This node will force itself to monophonic (regardless of the poly parameter
* passed to constructor) if the parent of the patch it's representing a port
* on has a different polyphony than the patch (since connecting mismatched
* polyphonies is impossible).
