expose scripting input types for objects/classes

yc

Classes or Objects should be exposable as a scripting input type, especially for arrays of them.

EXAMPLE: In the ML Multiple Object Templates, see BBoxBuilder.js - imagine if instead of having to write out for every single object type:

//@input bool cup
//@input Asset.Material cupColorFilter
//@input SceneObject cupSceneObject

and

    detectableClasses.push({
        enabled: script.cup,
        colorFilter: script.cupColorFilter,
        model: script.cupSceneObject,
        index: 1,
        label: "Cup",
    });

etc

it's simply

//@input Object.DetectableClass[] detectableClass

where each defined parameter in the class is exposed accordingly\

(This is available in Unity.)
