Cannot easily instantiate objects/create objects of specified type

[evanjs]

Problem

As originally mentioned in #297

I am trying to instantiate nodes (esp. objects) based on other node types.

As mentioned in the linked discussion, I am currently unable to do so using this library.

While I can create e.g. two distinct empty objects named Machine One and Machine Two, when I try to assign them to a type via has_type_definition, not even mandatory properties are created for me.

If I use has_component, the properties are created, but share the same instance across the objects with those components, which is not what I want.

If I understand the behavior of has_component correctly, I figure it is not what I should be using here.
In addition, it sounds like has_type_definition is closer to what I want, but it will not create any properties for me on the new object.

I wanted to verify whether:

• I am using the library incorrectly

  or

• The library currently doesn't have an instantiate function.

If I understand correctly, and this library does not currently have an instantiate function, then I would need to populate all properties by hand each time I instantiate an object.

I would also need a recursive create_instance function.
