From 30c08ba655330232767554c48bda1975bfb5628c Mon Sep 17 00:00:00 2001
From: David Robillard <d@drobilla.net>
Date: Fri, 11 Aug 2006 03:24:57 +0000
Subject: - Changed IO's vector<Port*>'s to PortList - Added new Port classes,
 code to drive them - Added PortList, which is a filthy mess ATM (nevermind
 that, it's the interface that's important at this stage) - Added ChanCount,
 though it isn't very thoroughly used yet.  That's the next step.... - Fixed a
 few bugs relating to loading sessions saved with trunk - Fixed a few random
 other bugs

Slowly working towards type agnosticism while keeping all the former code/logic intact is the name of the game here

Warning:  Removing ports is currently (intentionally) broken due solely to laziness.
