Impliment Class Property To Accept Class As Type

[rdlaitila]

Implement functionality to allow a class property to have a type of another class. For example:

local MyClass = require('MyClass')

local MyOtherClass = upperclass:define("MyOtherClass")

property : myClassProperty {
    nil;
    get='public';
    set='private';
    type=MyClass
}

function public:__construct()
    self.myClassProperty = MyClass()
end

return upperclass:compile(MyOtherClass)

When a class property is attempted to be set, it will check if the input value's class name (CLASS.imp.name) matches the class name of the property's type field. Ex:

if INPUT_VALUE.__imp__.name == TYPE_VALUE.__imp__.name then
    -- Allow set
end

The type field must be unquoted with the lua variable containing the class definition.
