CL - List and Dict Initializers

[AutumnThyme]

Similar to C#, JS, and Python, we should allow collections to be initialized with values.

class Main
{
    # Public variable should have a corresponding default array entry in Mode/Map editor veiw using JSON as the format.
    ModeVariable = List();

    # Second public variable uses a gameobject selector, on running, all gameobjects should be added to the list (or all ids if that prior isn't feasible).
    @MultiGameObjectSelector
    GameObjectVariable = List();

    # Private variables can use initializers. (Use whatever version is picked from the Init function).
    _privateVariable1 = List(['a', 'b', 'c']);

    function Init()
    {
        # Implement one of the following versions of list initializers.

        # version 1 syntactic sugar replaces [expr, expr, expr] with List(expr, expr, expr, ...) -> must modify list to have a secondary constructor that takes in objects
        localVariable1 = ['a', 'b', 'c'];
        localVariable2 = List(['a', 'b', 'c']);

        # version 2 likely use syntactic sugar to replace List() { expr, expr, expr } with List(expr, expr, expr, ...) -> must modify list to have a secondary constructor that takes in objects
        localVariable3 = List() { 'a', 'b', 'c' };
    }
}
