+ * 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).
