Version 3.0.1

• Added __len, __ipairs and __pairs metamethods for Lua 5.2

Version 3.0

• Anything that behaves reasonably like a class can be a class (no internal list of classes)
• The class global function is now just the return value of require 'middleclass'. It is a callable table, but works exactly as before.
• The global variable Object becomes class.Object
• The global function instanceOf becomes class.Object.isInstanceOf. Parameter order is reversed.
• The global function subclassOf becomes class.Object.static.isSubclassOf. Parameter order is reversed.
• The global function implements becomes class.Object.static.implements. Parameter order is reversed.
• Specs have been translated from telescope to busted

Version 2.0

• Static methods are now separated from instance methods
• class.superclass has now become class.super
• It's now possible to do class.subclasses
• middleclass is now a single file; init.lua has dissapeared
• license is changed from BSD to MIT. License included in source FTW
