[FEATURE REQUEST] Parent Child Entity Relation

[TheEmperorE2]

Hi there. In future if you have time for this. I think this feature is very handy.

If want to make ex.: Entity "Character" with multiple sprites moved by parent.

@TheEmperorE2 Hello, this is something that we are definitely going to be doing shortly.
We will be creating a new component called Relationship and all entities will have this for the Entity class by default.
It will be something like this:

namespace SCION_CORE::ECS
{
	struct Relationship
	{
		std::size_t numChildren{ 0 }; // Optional
		entt::entity firstChild{ entt::null };
		entt::entity prevSibling{ entt::null };
		entt::entity nextSibling{ entt::null };
		entt::entity parent{ entt::null };
	};
}

Then we will need to also add a local position to the transform component. Because we will need that to offset the child from the parent position.
