 Contains functions for easily defining and instantiating classes in Lua.
 
 First make sure you have this in your code:
 require("class.lua")
 
 Define a new class with the newClass() function:
 NewClass = newClass()
 
 Instantiate an new instance of the class with the new() method:
 newInstance = NewClass:new()
 
 Add methods to the class like this:
 function NewClass:newMethod()
 	print("New method")
 end
 
 Call methods of an instance of a class like this:
 newInstance:newMethod() -- prints "New method"
 
 Add a constructor to the class like this:
 function NewClass:init()
 	print("New instance created")
 end
 
 newInstance2 = NewClass:new() -- prints "New instance created"
 
 Use constructor parameters like this:
 function NewClass:init(par)
 	print("New instance: " .. par)
 end
 
 newInstance3 = NewClass:new("hello") -- prints "New instance: hello"
 
 Create subclasses like this:
 Subclass = newClass(NewClass)
 
 subclassInstance = Subclass:new("hi") -- prints "New instance: hi"
 
 Get the class of an instance like this:
 subclassInstance.instanceOf
 
 --]]
 
 function newClass(parent)
 	class = {} -- Method table
-	if not Class then
+	if Class then
-		parent = class
+		setmetatable(class, {__index = parent or Class}) -- Inherit from parent
-	elseif not parent then
+
-		parent = Class
+
 end
-	class.mt = {__index = class} -- Inherited metatable
+
-	setmetatable(class, parent.mt) -- Inherit from parent
+
 
 function Class:new(...) -- Class constructor
 	instance = setmetatable({}, {__index = self})
 	instance:init(...)
 	instance.instanceOf = self
 	return instance
-	instance = setmetatable({}, self.mt)
+
 
 function Class:init() -- Instance constructor
 end
